According to the versions of the glibc packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - stdlib/canonicalize.c in the GNU C Library (aka glibc     or libc6) 2.27 and earlier, when processing very long     pathname arguments to the realpath function, could     encounter an integer overflow on 32-bit architectures,     leading to a stack-based buffer overflow and,     potentially, arbitrary code execution.(CVE-2018-11236)

  - An AVX-512-optimized implementation of the mempcpy     function in the GNU C Library (aka glibc or libc6) 2.27     and earlier may write data beyond the target buffer,     leading to a buffer overflow in
    __mempcpy_avx512_no_vzeroupper.(CVE-2018-11237)

  - elf/dl-load.c in the GNU C Library (aka glibc or libc6)     2.19 through 2.26 mishandles RPATH and RUNPATH     containing $ORIGIN for a privileged (setuid or     AT_SECURE) program, which allows local users to gain     privileges via a Trojan horse library in the current     working directory, related to the fillin_rpath and     decompose_rpath functions. This is associated with     misinterpretion of an empty RPATH/RUNPATH token as the     './' directory. NOTE: this configuration of     RPATH/RUNPATH for a privileged program is apparently     very uncommon most likely, no such program is shipped     with any common Linux distribution.(CVE-2017-16997)

  - A heap-based buffer overflow was found in glibc's
    __nss_hostname_digits_dots() function, which is used by     the gethostbyname() and gethostbyname2() glibc function     calls. A remote attacker able to make an application     call either of these functions could use this flaw to     execute arbitrary code with the permissions of the user     running the application.(CVE-2015-0235)

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

  - An integer overflow vulnerability was found in     hcreate() and hcreate_r() functions which could result     in an out-of-bounds memory access. This could lead to     application crash or, potentially, arbitrary code     execution.(CVE-2015-8778)

  - A stack-based buffer overflow was found in the way the     libresolv library performed dual A/AAAA DNS queries. A     remote attacker could create a specially crafted DNS     response which could cause libresolv to crash or,     potentially, execute code with the permissions of the     user running the library. Note: this issue is only     exposed when libresolv is called from the nss_dns NSS     service module.(CVE-2015-7547)

  - A flaw was found in the regular expression matching     routines that process multibyte character input. If an     application utilized the glibc regular expression     matching mechanism, an attacker could provide     specially-crafted input that, when processed, would     cause the application to crash.(CVE-2013-0242)

  - A flaw was found in the way memory was being allocated     on the stack for user space binaries. If heap (or     different memory region) and stack memory regions were     adjacent to each other, an attacker could use this flaw     to jump over the stack guard gap, cause controlled     memory corruption on process stack or the adjacent     memory region, and thus increase their privileges on     the system. This is glibc-side mitigation which blocks     processing of LD_LIBRARY_PATH for programs running in     secure-execution mode and reduces the number of     allocations performed by the processing of LD_AUDIT,     LD_PRELOAD, and LD_HWCAP_MASK, making successful     exploitation of this issue more     difficult.(CVE-2017-1000366)

  - The DNS stub resolver in the GNU C Library (aka glibc     or libc6) before version 2.26, when EDNS support is     enabled, will solicit large UDP responses from name     servers, potentially simplifying off-path DNS spoofing     attacks due to IP fragmentation.(CVE-2017-12132)

  - It was found that the files back end of Name Service     Switch (NSS) did not isolate iteration over an entire     database from key-based look-up API calls. An     application performing look-ups on a database while     iterating over it could enter an infinite loop, leading     to a denial of service.(CVE-2014-8121)

  - Stack-based buffer overflow in the getaddrinfo function     in sysdeps/posix/getaddrinfo.c in the GNU C Library     (aka glibc or libc6) allows remote attackers to cause a     denial of service (crash) via vectors involving hostent     conversion. NOTE: this vulnerability exists because of     an incomplete fix for CVE-2013-4458.(CVE-2016-3706)

  - In glibc 2.26 and earlier there is confusion in the     usage of getcwd() by realpath() which can be used to     write before the destination buffer leading to a buffer     underflow and potential code     execution.(CVE-2018-1000001)

  - Stack-based buffer overflow in string/strcoll_l.c in     the GNU C Library (aka glibc or libc6) 2.17 and earlier     allows context-dependent attackers to cause a denial of     service (crash) or possibly execute arbitrary code via     a long string that triggers a malloc failure and use of     the alloca function.(CVE-2012-4424)

  - It was found that the dynamic loader did not sanitize     the LD_POINTER_GUARD environment variable. An attacker     could use this flaw to bypass the pointer guarding     protection on set-user-ID or set-group-ID programs to     execute arbitrary code with the permissions of the user     running the application.(CVE-2015-8777)

  - The glob function in glob.c in the GNU C Library (aka     glibc or libc6) before 2.27 contains a buffer overflow     during unescaping of user names with the ~     operator.(CVE-2017-15804)

  - res_query in libresolv in glibc before 2.25 allows     remote attackers to cause a denial of service (NULL     pointer dereference and process crash).(CVE-2015-5180)

  - pt_chown in GNU C Library (aka glibc or libc6) before     2.18 does not properly check permissions for tty files,     which allows local users to change the permission on     the files and obtain access to arbitrary     pseudo-terminals by leveraging a FUSE file     system.(CVE-2013-2207)

  - A stack overflow flaw was found in glibc's swscanf()     function. An attacker able to make an application call     the swscanf() function could use this flaw to crash     that application or, potentially, execute arbitrary     code with the permissions of the user running the     application.(CVE-2015-1473)

  - It was found that getaddrinfo() did not limit the     amount of stack memory used during name resolution. An     attacker able to make an application resolve an     attacker-controlled hostname or IP address could     possibly cause the application to exhaust all stack     memory and crash.(CVE-2013-4458)

  - A heap-based buffer overflow was found in glibc's
    __nss_hostname_digits_dots() function, which is used by     the gethostbyname() and gethostbyname2() glibc function     calls. A remote attacker able to make an application     call either of these functions could use this flaw to     execute arbitrary code with the permissions of the user     running the application.(CVE-2015-0235)

  - Multiple integer overflow flaws, leading to heap-based     buffer overflows, were found in glibc's memory     allocator functions (pvalloc, valloc, and memalign). If     an application used such a function, it could cause the     application to crash or, potentially, execute arbitrary     code with the privileges of the user running the     application.(CVE-2013-4332)

  - An integer overflow in the implementation of the     posix_memalign in memalign functions in the GNU C     Library (aka glibc or libc6) 2.26 and earlier could     cause these functions to return a pointer to a heap     area that is too small, potentially leading to heap     corruption.(CVE-2018-6485)

  - A stack based buffer overflow vulnerability was found     in the catopen() function. An excessively long string     passed to the function could cause it to crash or,     potentially, execute arbitrary code.(CVE-2015-8779)

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

Use after free vulnerability was reported in PHP DateTimeZone.
(CVE-2015-0273)

An updated rhev-hypervisor6 package that fixes multiple security issues is now available for Red Hat Enterprise Virtualization 3.

Red Hat Product Security has rated this update as having Critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: a subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions.

A heap-based buffer overflow was found in glibc's
__nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls. A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. (CVE-2015-0235)

A race condition flaw was found in the way the Linux kernel's KVM subsystem handled PIT (Programmable Interval Timer) emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host. (CVE-2014-3611)

A flaw was found in the way OpenSSL handled fragmented handshake packets. A man-in-the-middle attacker could use this flaw to force a TLS/SSL server using OpenSSL to use TLS 1.0, even if both the client and the server supported newer protocol versions. (CVE-2014-3511)

A memory leak flaw was found in the way an OpenSSL handled failed session ticket integrity checks. A remote attacker could exhaust all available memory of an SSL/TLS or DTLS server by sending a large number of invalid session tickets to that server. (CVE-2014-3567)

It was found that the Linux kernel's KVM subsystem did not handle the VM exits gracefully for the invept (Invalidate Translations Derived from EPT) and invvpid (Invalidate Translations Based on VPID) instructions. On hosts with an Intel processor and invept/invppid VM exit support, an unprivileged guest user could use these instructions to crash the guest. (CVE-2014-3645, CVE-2014-3646)

Red Hat would like to thank Qualys for reporting the CVE-2015-0235 issue, Lars Bull of Google for reporting the CVE-2014-3611 issue, and the Advanced Threat Research team at Intel Security for reporting the CVE-2014-3645 and CVE-2014-3646 issues.

Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package.

Versions of PHP 5.4.x earlier than 5.4.38, 5.5.x earlier than 5.5.22, or 5.6.x earlier than 5.6.6 are exposed to the following issues :

  - A heap-based buffer overflow flaw in the GNU C Library (glibc) due to improperly validating user-supplied input in the glibc functions __nss_hostname_digits_dots(), gethostbyname(), and gethostbyname2(). This allows a remote attacker to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (GHOST) (Bug 68925 / CVE-2015-0235)

  - A use-after-free flaw exists in the function php_date_timezone_initialize_from_hash() within the 'ext/date/php_date.c' script. An attacker can exploit this to access sensitive information or crash applications linked to PHP. (Bug 68942 / CVE-2015-0273)

  - A use-after-free flaw exists in the function 'phar_rename_archive' in the source file 'phar_object.c'. An attacker can cause a denial of service or possibly have unspecified other impact via vectors that trigger an attempted renaming of a Phar archive to the name of an existing file. (Bug 68901 / CVE-2015-2301)

  - A heap-based buffer overflow flaw affects the 'enchant_broker_request_dict' function in the source file 'ext/enchant/enchant.c'. This allows remote attackers to execute arbitrary code via vectors that trigger creation of multiple dictionaries. (Bug 68552 / CVE-2014-9705)
