 Mandriva Linux Security Advisory                         MDVSA-2011:179
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : glibc
 Date    : November 25, 2011
 Affected: 2011.
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities was discovered and fixed in glibc:
 
 The addmntent function in the GNU C Library (aka glibc or libc6) 2.13
 and earlier does not report an error status for failed attempts to
 write to the /etc/mtab file, which makes it easier for local users
 to trigger corruption of this file, as demonstrated by writes from
 a process with a small RLIMIT_FSIZE value, a different vulnerability
 than CVE-2010-0296 (CVE-2011-1089).
 
 Integer overflow in posix/fnmatch.c in the GNU C Library (aka glibc or
 libc6) 2.13 and earlier allows context-dependent attackers to cause a
 denial of service (application crash) via a long UTF8 string that is
 used in an fnmatch call with a crafted pattern argument, a different
 vulnerability than CVE-2011-1071 (CVE-2011-1659).
 
 crypt_blowfish before 1.1, as used in glibc on certain platforms,
 does not properly handle 8-bit characters, which makes it easier
 for context-dependent attackers to determine a cleartext password by
 leveraging knowledge of a password hash (CVE-2011-2483).
 
 The updated packages have been patched to correct these issues.
