According to the versions of the glibc packages installed, the EulerOS Virtualization 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 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)

Updated glibc packages that fix multiple security issues are now available for Red Hat Enterprise Linux 7.1 Extended Update Support.

Red Hat Product Security has rated this update as having Important 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 glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.

It was discovered that the nss_files backend for the Name Service Switch in glibc would return incorrect data to applications or corrupt the heap (depending on adjacent heap contents). A local attacker could potentially use this flaw to execute arbitrary code on the system.
(CVE-2015-5277)

It was discovered that, under certain circumstances, glibc's getaddrinfo() function would send DNS queries to random file descriptors. An attacker could potentially use this flaw to send DNS queries to unintended recipients, resulting in information disclosure or data loss due to the application encountering corrupted data.
(CVE-2013-7423)

A buffer overflow flaw was found in the way glibc's gethostbyname_r() and other related functions computed the size of a buffer when passed a misaligned buffer as input. An attacker able to make an application call any of these functions with a misaligned buffer could use this flaw to crash the application or, potentially, execute arbitrary code with the permissions of the user running the application.
(CVE-2015-1781)

A heap-based buffer overflow flaw and a stack overflow flaw were found in glibc's swscanf() function. An attacker able to make an application call the swscanf() function could use these flaws to crash that application or, potentially, execute arbitrary code with the permissions of the user running the application. (CVE-2015-1472, CVE-2015-1473)

The CVE-2015-5277 issue was discovered by Sumit Bose and Lukas Slebodnik of Red Hat, and the CVE-2015-1781 issue was discovered by Arjun Shankar of Red Hat.

Updated glibc packages fix security vulnerabilities :

Stephane Chazelas discovered that directory traversal issue in locale handling in glibc. glibc accepts relative paths with .. components in the LC_* and LANG variables. Together with typical OpenSSH configurations (with suitable AcceptEnv settings in sshd_config), this could conceivably be used to bypass ForceCommand restrictions (or restricted shells), assuming the attacker has sufficient level of access to a file system location on the host to create crafted locale definitions there (CVE-2014-0475).

David Reid, Glyph Lefkowitz, and Alex Gaynor discovered a bug where posix_spawn_file_actions_addopen fails to copy the path argument (glibc bz #17048) which can, in conjunction with many common memory management techniques from an application, lead to a use after free, or other vulnerabilities (CVE-2014-4043).

This update also fixes the following issues: x86: Disable x87 inline functions for SSE2 math (glibc bz #16510) malloc: Fix race in free() of fastbin chunk (glibc bz #15073)

Tavis Ormandy discovered a heap-based buffer overflow in the transliteration module loading code. As a result, an attacker who can supply a crafted destination character set argument to iconv-related character conversation functions could achieve arbitrary code execution.

This update removes support of loadable gconv transliteration modules.
Besides the security vulnerability, the module loading code had functionality defects which prevented it from working for the intended purpose (CVE-2014-5119).

Adhemerval Zanella Netto discovered out-of-bounds reads in additional code page decoding functions (IBM933, IBM935, IBM937, IBM939, IBM1364) that can be used to crash the systems, causing a denial of service conditions (CVE-2014-6040).

The function wordexp() fails to properly handle the WRDE_NOCMD flag when processing arithmetic inputs in the form of '$((... ))' where '...' can be anything valid. The backticks in the arithmetic epxression are evaluated by in a shell even if WRDE_NOCMD forbade command substitution. This allows an attacker to attempt to pass dangerous commands via constructs of the above form, and bypass the WRDE_NOCMD flag. This update fixes the issue (CVE-2014-7817).

The vfprintf function in stdio-common/vfprintf.c in GNU C Library (aka glibc) 2.5, 2.12, and probably other versions does not properly restrict the use of the alloca function when allocating the SPECS array, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (crash) or possibly execute arbitrary code via a crafted format string using positional parameters and a large number of format specifiers (CVE-2012-3406).

The nss_dns implementation of getnetbyname could run into an infinite loop if the DNS response contained a PTR record of an unexpected format (CVE-2014-9402).

Also glibc lock elision (new feature in glibc 2.18) has been disabled as it can break glibc at runtime on newer Intel hardware (due to hardware bug)

Under certain conditions wscanf can allocate too little memory for the to-be-scanned arguments and overflow the allocated buffer (CVE-2015-1472).

The incorrect use of '__libc_use_alloca (newsize)' caused a different (and weaker) policy to be enforced which could allow a denial of service attack (CVE-2015-1473).

Several vulnerabilities have been fixed in eglibc, Debian's version of the GNU C library.

#553206 CVE-2015-1472 CVE-2015-1473

The scanf family of functions do not properly limit stack allocation, which allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code.

CVE-2012-3405

The printf family of functions do not properly calculate a buffer length, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service.

CVE-2012-3406

The printf family of functions do not properly limit stack allocation, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (crash) or possibly execute arbitrary code via a crafted format string.

CVE-2012-3480

Multiple integer overflows in the strtod, strtof, strtold, strtod_l, and other related functions allow local users to cause a denial of service (application crash) and possibly execute arbitrary code via a long string, which triggers a stack-based buffer overflow.

CVE-2012-4412

Integer overflow in the strcoll and wcscoll functions allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow.

CVE-2012-4424

Stack-based buffer overflow in the strcoll and wcscoll functions 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-2013-0242

Buffer overflow in the extend_buffers function in the regular expression matcher allows context-dependent attackers to cause a denial of service (memory corruption and crash) via crafted multibyte characters.

CVE-2013-1914 CVE-2013-4458

Stack-based buffer overflow in the getaddrinfo function allows remote attackers to cause a denial of service (crash) via a hostname or IP address that triggers a large number of domain conversion results.

CVE-2013-4237

readdir_r allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a malicious NTFS image or CIFS service.

CVE-2013-4332

Multiple integer overflows in malloc/malloc.c allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the pvalloc, valloc, posix_memalign, memalign, or aligned_alloc functions.

CVE-2013-4357

The getaliasbyname, getaliasbyname_r, getaddrinfo, getservbyname, getservbyname_r, getservbyport, getservbyport_r, and glob functions do not properly limit stack allocation, which allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code.

CVE-2013-4788

When the GNU C library is statically linked into an executable, the PTR_MANGLE implementation does not initialize the random value for the pointer guard, so that various hardening mechanisms are not effective.

CVE-2013-7423

The send_dg function in resolv/res_send.c does not properly reuse file descriptors, which allows remote attackers to send DNS queries to unintended locations via a large number of requests that trigger a call to the getaddrinfo function.

CVE-2013-7424

The getaddrinfo function may attempt to free an invalid pointer when handling IDNs (Internationalised Domain Names), which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code.

CVE-2014-4043

The posix_spawn_file_actions_addopen function does not copy its path argument in accordance with the POSIX specification, which allows context-dependent attackers to trigger use-after-free vulnerabilities.

For the oldstable distribution (squeeze), these problems have been fixed in version 2.11.3-4+deb6u5.

For the stable distribution (wheezy), these problems were fixed in version 2.13-38+deb7u8 or earlier.

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

Arnaud Le Blanc discovered that the GNU C Library incorrectly handled file descriptors when resolving DNS queries under high load. This may cause a denial of service in other applications, or an information leak. This issue only affected Ubuntu 10.04 LTS, Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2013-7423)

It was discovered that the GNU C Library incorrectly handled receiving a positive answer while processing the network name when performing DNS resolution. A remote attacker could use this issue to cause the GNU C Library to hang, resulting in a denial of service.
(CVE-2014-9402)

Joseph Myers discovered that the GNU C Library wscanf function incorrectly handled memory. A remote attacker could possibly use this issue to cause the GNU C Library to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 14.10. (CVE-2015-1472, CVE-2015-1473).

Several vulnerabilities have been fixed in eglibc, Debian's version of the GNU C library :

  - CVE-2012-3406     The vfprintf function in stdio-common/vfprintf.c in GNU     C Library (aka glibc) 2.5, 2.12, and probably other     versions does not 'properly restrict the use of' the     alloca function when allocating the SPECS array, which     allows context-dependent attackers to bypass the     FORTIFY_SOURCE format-string protection mechanism and     cause a denial of service (crash) or possibly execute     arbitrary code via a crafted format string using     positional parameters and a large number of format     specifiers, a different vulnerability than CVE-2012-3404     and CVE-2012-3405.

  - CVE-2013-7424     An invalid free flaw was found in glibc's getaddrinfo()     function when used with the AI_IDN flag. A remote     attacker able to make an application call this function     could use this flaw to execute arbitrary code with the     permissions of the user running the application. Note     that this flaw only affected applications using glibc     compiled with libidn support.

  - CVE-2014-4043     The posix_spawn_file_actions_addopen function in glibc     before 2.20 does not copy its path argument in     accordance with the POSIX specification, which allows     context-dependent attackers to trigger use-after-free     vulnerabilities.

  - CVE-2014-9402     The getnetbyname function in glibc 2.21 or earlier will     enter an infinite loop if the DNS backend is activated     in the system Name Service Switch configuration, and the     DNS resolver receives a positive answer while processing     the network name.

  - CVE-2015-1472 / CVE-2015-1473     Under certain conditions wscanf can allocate too little     memory for the to-be-scanned arguments and overflow the     allocated buffer. The incorrect use of     '__libc_use_alloca (newsize)' caused a different (and     weaker) policy to be enforced which could allow a denial     of service attack.
