Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2012-4412)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Integer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier. A remote attacker can use a long string to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Buffer overflow (CVE-ID: CVE-2013-4237)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

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.


3) Input validation error (CVE-ID: CVE-2014-5119)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Off-by-one error in the __gconv_translit_find function in gconv_trans.c in GNU C Library (aka glibc) allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via vectors related to the CHARSET environment variable and gconv transliteration modules.
