Security Bulletin: Two (2) Vulnerabilities in glibc affect IBM FlashSystem (and TMS RAMSAN) 710, 720, 810, and 820 systems (CVE-2014-5119 and CVE-2014-0475)

Security Bulletin

Summary

Vulnerabilities have been found in glibc packages, which contain standard C libraries used by multiple programs on the system. They affect the IBM FlashSystem (and TMS RAMSAN) 710, 720, 810, and 820 products. These vulnerabilities, if exploited, could allow execution of arbitrary code on the system with root privileges

Vulnerability Details

1. CVE-ID: CVE-2014-5119
DESCRIPTION: The GNU C Library (glibc) is vulnerable to a heap-based buffer overflow, caused by an off-by-one error in the __gconv_translit_find() function. By setting the CHARSET environment variable to a malicious value, a local attacker could exploit this vulnerability to overflow a buffer and execute arbitrary code on the system with root privileges.
CVSS Base Score: 7.2
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95044 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: CVSS Vector: (AV:L/AC:L/Au:N/C:C/I:C/A:C)

2. CVE-ID: CVE-2014-0475
DESCRIPTION: Multiple directory traversal vulnerabilities in GNU C Library (aka glibc or libc6) before 2.20 allow context-dependent attackers to bypass ForceCommand restrictions and possibly have other unspecified impact via a .. (dot dot) in a (1) LC_*, (2) LANG, or other locale environment variable.
CVSS Base Score: No xForce Score (NVD: 6.8)
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/94452 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:P)
