CVSS Base Vector:
AV:N/AC:M/Au:N/C:C/I:C/A:C
Technical Details:
The following Linux Distribution Package is affected: FreeBSD
CVE-2011-2895
The LZW decompressor in (1) the BufCompressedFill function in
fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2)
compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before
3.8, FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before
5.1.1, FreeType 2.1.9, and other products, does not properly handle
code words that are absent from the decompression table when
encountered, which allows context-dependent attackers to trigger an
infinite loop or a heap-based buffer overflow, and possibly execute
arbitrary code, via a crafted compressed stream, a related issue to
CVE-2006-1168 and CVE-2011-2896.

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
