Mandriva Linux Security Advisory : glibc (MDVSA-2013:283)

high Nessus Plugin ID 71092

Language:

Synopsis

The remote Mandriva Linux host is missing one or more security updates.

Description

Updated glibc packages fixes the following security issues :

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).

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).
NOTE! This is fixed by removing pt_chown wich may break chroots if their devpts was not mounted correctly (make sure to mount the devpts correctly with gid=5).

sysdeps/posix/readdir_r.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a crafted (1) NTFS or (2) CIFS image (CVE-2013-4237).

Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the (1) pvalloc, (2) valloc, (3) posix_memalign, (4) memalign, or (5) aligned_alloc functions (CVE-2013-4332).

A stack (frame) overflow flaw, which led to a denial of service (application crash), was found in the way glibc's getaddrinfo() function processed certain requests when called with AF_INET6. A similar flaw to CVE-2013-1914, this affects AF_INET6 rather than AF_UNSPEC (CVE-2013-4458).

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).

Other fixes in this update :

 - Correct the processing of '\x80' characters in crypt_freesec.c

 - fix typo in nscd.service

Solution

Update the affected packages.
