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

  - elf/dl-load.c in ld.so in the GNU C Library (aka glibc     or libc6) through 2.11.2, and 2.12.x through 2.12.1,     does not properly handle a value of $ORIGIN for the     LD_AUDIT environment variable, which allows local users     to gain privileges via a crafted dynamic shared object     (DSO) located in an arbitrary directory. (CVE-2010-3847)

  - ld.so in the GNU C Library (aka glibc or libc6) before     2.11.3, and 2.12.x before 2.12.2, does not properly     restrict use of the LD_AUDIT environment variable to     reference dynamic shared objects (DSOs) as audit     objects, which allows local users to gain privileges by     leveraging an unsafe DSO located in a trusted library     directory, as demonstrated by libpcprofile.so.
    (CVE-2010-3856)

  - Integer 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, which triggers a heap-based buffer overflow.
    (CVE-2012-4412)

  - 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)

  - 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)

  - 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-2013-1914, CVE-2013-4458)

  - 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)

  - An out-of-bounds write flaw was found in the way the     glibc's readdir_r() function handled file system entries     longer than the NAME_MAX character constant. A remote     attacker could provide a specially crafted NTFS or CIFS     file system that, when processed by an application using     readdir_r(), would cause that application to crash or,     potentially, allow the attacker to execute arbitrary     code with the privileges of the user running the     application. (CVE-2013-4237)

  - 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)

  - The PTR_MANGLE implementation in the GNU C Library (aka     glibc or libc6) 2.4, 2.17, and earlier, and Embedded     GLIBC (EGLIBC) does not initialize the random value for     the pointer guard, which makes it easier for context-     dependent attackers to control execution flow by     leveraging a buffer-overflow vulnerability in an     application and using the known zero value pointer guard     to calculate a pointer address. (CVE-2013-4788)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Integer 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, which triggers a heap-based buffer overflow. (CVE-2012-4412)

Note that Nessus relies on the presence of the package as reported by the vendor.
