Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - glibc: Incorrect handling of RPATH in elf/dl-load.c can be used to execute code loaded from arbitrary     libraries (CVE-2017-16997)

  - glibc: regular-expression match via proceed_next_node in posix/regexec.c leads to heap-based buffer over-     read (CVE-2019-9169)

  - In the GNU C Library (aka glibc or libc6) before 2.28, parse_reg_exp in posix/regcomp.c misparses     alternatives, which allows attackers to cause a denial of service (assertion failure and application exit)     or trigger an incorrect result by attempting a regular-expression match. (CVE-2009-5155)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - glibc: Incorrect handling of RPATH in elf/dl-load.c can be used to execute code loaded from arbitrary     libraries (CVE-2017-16997)

  - glibc: regular-expression match via proceed_next_node in posix/regexec.c leads to heap-based buffer over-     read (CVE-2019-9169)

  - In the GNU C Library (aka glibc or libc6) before 2.28, parse_reg_exp in posix/regcomp.c misparses     alternatives, which allows attackers to cause a denial of service (assertion failure and application exit)     or trigger an incorrect result by attempting a regular-expression match. (CVE-2009-5155)

The remote Redhat Enterprise Linux 4 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - glibc: posix_spawn_file_actions_addopen fails to copy the path argument (CVE-2014-4043)

  - glibc: heap/stack gap jumping via unbounded stack allocations (CVE-2017-1000366)

  - ld.so in the GNU C Library (aka glibc or libc6) 2.13 and earlier expands the $ORIGIN dynamic string token     when RPATH is composed entirely of this token, which might allow local users to gain privileges by     creating a hard link in an arbitrary directory to a (1) setuid or (2) setgid program with this RPATH     value, and then executing the program with a crafted value for the LD_PRELOAD environment variable, a     different vulnerability than CVE-2010-3847 and CVE-2011-0536. NOTE: it is not expected that any standard     operating-system distribution would ship an applicable setuid or setgid program. (CVE-2011-1658)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has glibc packages installed that are affected by multiple vulnerabilities:

  - 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-2014-4043)

  - In the GNU C Library (aka glibc or libc6) through 2.29, check_dst_limits_calc_pos_1 in posix/regexec.c has     Uncontrolled Recursion, as demonstrated by '(\227|)(\\1\\1|t1|\\\2537)+' in grep. (CVE-2018-20796)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has glibc packages installed that are affected by multiple vulnerabilities:

  - 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-2014-4043)

  - In the GNU C Library (aka glibc or libc6) through 2.29, check_dst_limits_calc_pos_1 in posix/regexec.c has     Uncontrolled Recursion, as demonstrated by '(\227|)(\\1\\1|t1|\\\2537)+' in grep. (CVE-2018-20796)

  - On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the     LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition,     allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass     ASLR for a setuid program. (CVE-2019-19126)

  - The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-     byte input sequences in the EUC-KR encoding, may have a buffer over-read. (CVE-2019-25013)

  - The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range     reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when     passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to     sysdeps/ieee754/ldbl-96/e_rem_pio2l.c. (CVE-2020-10029)

  - sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-     based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with     a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to     sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because     of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words,     the reference to 2.23 is intentional despite the mention of Fixed for glibc 2.33 in the 26649 reference.
    (CVE-2020-29573)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

  - Stack-based buffer overflow in the clntudp_call     function in sunrpc/clnt_udp.c in the GNU C Library (aka     glibc or libc6) allows remote servers to cause a denial     of service (crash) or possibly unspecified other impact     via a flood of crafted ICMP and UDP     packets.(CVE-2016-4429)

  - Integer overflow in the strxfrm function in the GNU C     Library (aka glibc or libc6) before 2.21 allows     context-dependent attackers to cause a denial of     service (crash) or possibly execute arbitrary code via     a long string, which triggers a stack-based buffer     overflow.(CVE-2015-8982)

  - 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-2014-4043)

  - 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)

  - A buffer overflow has been discovered in the GNU C     Library (aka glibc or libc6) in the
    __mempcpy_avx512_no_vzeroupper function when particular     conditions are met. An attacker could use this     vulnerability to cause a denial of service or     potentially execute code.(CVE-2018-11237)

  - In the GNU C Library (aka glibc or libc6) through 2.29,     proceed_next_node in posix/regexec.c has a heap-based     buffer over-read via an attempted case-insensitive     regular-expression match.(CVE-2019-9169)

  - The iconv program in the GNU C Library (aka glibc or     libc6) 2.25 and earlier, when invoked with the -c     option, enters an infinite loop when processing invalid     multi-byte input sequences, leading to a denial of     service.(CVE-2016-10228)

  - 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)

  - 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)

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.

The remote host is affected by the vulnerability described in GLSA-201503-04 (GNU C Library: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in the GNU C Library.
      Please review the CVE identifiers referenced below for details.
  Impact :

    A local attacker may be able to execute arbitrary code or cause a Denial       of Service condition,.
  Workaround :

    There is no known workaround at this time.

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.

New glibc packages are available for Slackware 14.1 and -current to fix security issues.

USN-2306-1 fixed vulnerabilities in the GNU C Library. On Ubuntu 10.04 LTS, the fix for CVE-2013-4357 introduced a memory leak in getaddrinfo. This update fixes the problem.

We apologize for the inconvenience.

Maksymilian Arciemowicz discovered that the GNU C Library incorrectly handled the getaddrinfo() function. An attacker could use this issue to cause a denial of service. This issue only affected Ubuntu 10.04 LTS. (CVE-2013-4357)

It was discovered that the GNU C Library incorrectly handled the getaddrinfo() function. An attacker could use this issue to cause a denial of service. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. (CVE-2013-4458)

Stephane Chazelas discovered that the GNU C Library incorrectly handled locale environment variables. An attacker could use this issue to possibly bypass certain restrictions such as the ForceCommand restrictions in OpenSSH. (CVE-2014-0475)

David Reid, Glyph Lefkowitz, and Alex Gaynor discovered that the GNU C Library incorrectly handled posix_spawn_file_actions_addopen() path arguments. An attacker could use this issue to cause a denial of service.
(CVE-2014-4043).

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

Updated glibc packages fix security issues :

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).

USN-2306-1 fixed vulnerabilities in the GNU C Library. On Ubuntu 10.04 LTS, the security update cause a regression in certain environments that use the Name Service Caching Daemon (nscd), such as those configured for LDAP or MySQL authentication. In these environments, the nscd daemon may need to be stopped manually for name resolution to resume working so that updates can be downloaded, including environments configured for unattended updates.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

glibc has been updated to fix one security issue that could have resulted in free-after-use situations.

More information can be found at http://seclists.org/oss-sec/2014/q2/519

This security issue has been fixed :

  - posix_spawn_file_actions_addopen fails to copy the path     argument (CVE-2014-4043) Also a regression from a     previous update has been fixed :

  - Don't ignore too long lines in nss_files (bnc#883217)
