Mandriva Update for t1lib MDVSA-2012:004 (t1lib)

Published: 2012-01-13 05:19:44
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:H/Au:N/C:C/I:C/A:C

Summary:
The remote host is missing an update for the 't1lib' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
t1lib on Mandriva Linux 2011.0, Mandriva Enterprise Server 5.2, Mandriva Linux 2010.1

Recommendations:
Please Install the Updated Packages.

Technical Details:
Multiple vulnerabilities has been found and corrected in t1lib: A heap-based buffer overflow flaw was found in the way AFM font file parser, used for rendering of DVI files, in GNOME evince document viewer and other products, processed line tokens from the given input stream. A remote attacker could provide a DVI file, with embedded specially-crafted font file, and trick the local user to open it with an application using the AFM font parser, leading to that particular application crash or, potentially, arbitrary code execution with the privileges of the user running the application. Different vulnerability than CVE-2010-2642 (CVE-2011-0433). t1lib 5.1.2 and earlier reads from invalid memory locations, which allows remote attackers to cause a denial of service (application crash) via a crafted Type 1 font in a PDF document, a different vulnerability than CVE-2011-0764 (CVE-2011-1552). Use-after-free vulnerability in t1lib 5.1.2 and earlier allows remote attackers to cause a denial of service (application crash) via a PDF document containing a crafted Type 1 font that triggers an invalid memory write, a different vulnerability than CVE-2011-0764 (CVE-2011-1553). Off-by-one error in t1lib 5.1.2 and earlier allows remote attackers to cause a denial of service (application crash) via a PDF document containing a crafted Type 1 font that triggers an invalid memory read, integer overflow, and invalid pointer dereference, a different vulnerability than CVE-2011-0764 (CVE-2011-1554). The updated Linux Distribution Packages have been patched to correct these issues.

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".
