 Mandriva Linux Security Advisory                         MDVSA-2013:283
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : glibc
 Date    : November 25, 2013
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem 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
