This update for the Linux Kernel 4.4.121-92_149 fixes several issues.

The following security issues were fixed :

CVE-2020-27786: Fixed a potential user after free which could have led to memory corruption or privilege escalation (bsc#1179616).

CVE-2020-28374: Fixed insufficient identifier checking in the LIO SCSI target code which could have been used by remote attackers to read or write files via directory traversal in an XCOPY request (bsc#1178684).

CVE-2020-25645: Fixed an issue where the traffic between two Geneve endpoints may have been unencrypted when IPsec was configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted (bsc#1177513).

CVE-2020-0429: Fixed a potential memory corruption due to a use after free which could have led local escalation of privilege with System execution privileges needed (bsc#1176931).

CVE-2020-1749: Fixed an issue in some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6 where the kernel was not correctly routing tunneled data over the encrypted link rather sending the data unencrypted (bsc#1165631).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of AOS installed on the remote host is prior to 5.20. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.20 advisory.

  - Vulnerability in the Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition product of Oracle Java     SE (component: Libraries). Supported versions that are affected are Java SE: 7u291, 8u281, 11.0.10, 16;
    Java SE Embedded: 8u281; Oracle GraalVM Enterprise Edition: 19.3.5, 20.3.1.2 and 21.0.0.2. Difficult to     exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to     compromise Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition. Successful attacks require human     interaction from a person other than the attacker. Successful attacks of this vulnerability can result in     unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded,     Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments     that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox     for security. (CVE-2021-2163)

  - Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow     unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5715)

  - Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized     disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5753)

  - Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow     unauthorized disclosure of information to an attacker with local user access via a side-channel analysis     of the data cache. (CVE-2017-5754)

  - An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI     subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the     pointer to an iscsi_transport struct in the kernel module's global variables. (CVE-2021-27363)

  - An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is     adversely affected by the ability of an unprivileged user to craft Netlink messages. (CVE-2021-27364)

  - An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a     Netlink message. (CVE-2021-27365)

  - Vulnerability in the Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition product of Oracle Java     SE (component: Libraries). Supported versions that are affected are Java SE: 7u291, 8u281, 11.0.10, 16;
    Java SE Embedded: 8u281; Oracle GraalVM Enterprise Edition: 19.3.5, 20.3.1.2 and 21.0.0.2. Difficult to     exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to     compromise Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition. Successful attacks of this     vulnerability can result in unauthorized creation, deletion or modification access to critical data or all     Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability     applies to Java deployments that load and run untrusted code (e.g., code that comes from the internet) and     rely on the Java sandbox for security. It can also be exploited by supplying untrusted data to APIs in the     specified Component. (CVE-2021-2161)

  - encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write     access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character     sequence. (CVE-2021-26937)

  - BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG     features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed,     but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or     tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-     TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server     environments that combine BIND servers with Active Directory domain controllers. The most likely outcome     of a successful exploitation of the vulnerability is a crash of the named process. However, remote code     execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11,     and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition.
    Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch (CVE-2020-8625)

  - A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification functions     (GOST DSA, EDDSA & ECDSA) result in the Elliptic Curve Cryptography point (ECC) multiply function being     called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to     force an invalid signature, causing an assertion failure or possible validation. The highest threat to     this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-20305)

  - In the Linux kernel before 5.3.9, there are multiple out-of-bounds write bugs that can be caused by a     malicious USB device in the Linux kernel HID drivers, aka CID-d9d4b1e46d95. This affects drivers/hid/hid-     axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c, drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,     drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c, drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,     drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-     tmff.c, and drivers/hid/hid-zpff.c. (CVE-2019-19532)

  - In create_pinctrl of core.c, there is a possible out of bounds read due to a use after free. This could     lead to local information disclosure with no additional execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-140550171     (CVE-2020-0427)

  - A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem     allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate     privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as     system availability. (CVE-2020-14351)

  - In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could     overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in     ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.
    (CVE-2020-25211)

  - A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may     be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE     tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from     this vulnerability is to data confidentiality. (CVE-2020-25645)

  - A flaw was found in the Linux kernel. A use-after-free was found in the way the console subsystem was     using ioctls KDGKBSENT and KDSKBSENT. A local user could use this flaw to get read memory access out of     bounds. The highest threat from this vulnerability is to data confidentiality. (CVE-2020-25656)

  - A flaw in ICMP packets in the Linux kernel may allow an attacker to quickly scan open UDP ports. This flaw     allows an off-path remote attacker to effectively bypass source port UDP randomization. Software that     relies on UDP source port randomization are indirectly affected as well on the Linux Based Products     (RUGGEDCOM RM1224: All versions between v5.0 and v6.4, SCALANCE M-800: All versions between v5.0 and v6.4,     SCALANCE S615: All versions between v5.0 and v6.4, SCALANCE SC-600: All versions prior to v2.1.3, SCALANCE     W1750D: v8.3.0.1, v8.6.0, and v8.7.0, SIMATIC Cloud Connect 7: All versions, SIMATIC MV500 Family: All     versions, SIMATIC NET CP 1243-1 (incl. SIPLUS variants): Versions 3.1.39 and later, SIMATIC NET CP 1243-7     LTE EU: Version (CVE-2020-25705)

  - In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking     in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal     in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker     has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are     proxied via an attacker-selected backstore. (CVE-2020-28374)

  - A locking issue was discovered in the tty subsystem of the Linux kernel through 5.9.13.
    drivers/tty/tty_jobctrl.c allows a use-after-free attack against TIOCSPGRP, aka CID-54ffccbf053b.
    (CVE-2020-29661)

  - In the Linux kernel 4.14 longterm through 4.14.165 and 4.19 longterm through 4.19.96 (and 5.x before 5.2),     there is a use-after-free (write) in the i915_ppgtt_close function in drivers/gpu/drm/i915/i915_gem_gtt.c,     aka CID-7dc40713618c. This is related to i915_gem_context_destroy_ioctl in     drivers/gpu/drm/i915/i915_gem_context.c. (CVE-2020-7053)

  - A flaw was found in the way memory resources were freed in the unix_stream_recvmsg function in the Linux     kernel when a signal was pending. This flaw allows an unprivileged local user to crash the system by     exhausting available memory. The highest threat from this vulnerability is to system availability.
    (CVE-2021-20265)

  - When responding to new h2c connection requests, Apache Tomcat versions 10.0.0-M1 to 10.0.0, 9.0.0.M1 to     9.0.41 and 8.5.0 to 8.5.61 could duplicate request headers and a limited amount of request body from one     request to another meaning user A and user B could both see the results of user A's request.
    (CVE-2021-25122)

  - The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to     9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be     used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published     prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to     this issue. (CVE-2021-25329)

  - In BIND 9.0.0 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 ->     9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND     9.17 development branch, when a vulnerable version of named receives a query for a record triggering the     flaw described above, the named process will terminate due to a failed assertion check. The vulnerability     affects all currently maintained BIND 9 branches (9.11, 9.11-S, 9.16, 9.16-S, 9.17) as well as all other     versions of BIND 9. (CVE-2021-25215)
