Red Hat 6: RHSA-2011-0009-01 Moderate Evince Buffer Overflow Threat

red hat
Calendar Grey January 6, 2011
Dist Redhat Esm H88
Red Hat has issued a security advisory addressing vulnerabilities in evince, specifically targeting moderate risks associated with buffer and integer overflow exploits.
Updated evince packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at

Summary

Evince is a document viewer.
An array index error was found in the DeVice Independent (DVI) renderer's PK and VF font file parsers. A DVI file that references a specially-crafted font file could, when opened, cause Evince to crash or, potentially, execute arbitrary code with the privileges of the user running Evince. (CVE-2010-2640, CVE-2010-2641)
A heap-based buffer overflow flaw was found in the DVI renderer's AFM font file parser. A DVI file that references a specially-crafted font file could, when opened, cause Evince to crash or, potentially, execute arbitrary code with the privileges of the user running Evince. (CVE-2010-2642)
An integer overflow flaw was found in the DVI renderer's TFM font file parser. A DVI file that references a specially-crafted font file could, when opened, cause Evince to crash or, potentially, execute arbitrary code with the privileges of the user running Evince. (CVE-2010-2643)
Note: The above issues are not exploitable unless an attacker can trick the user into installing a malicious font file.
Red Hat would like to thank the Evince development team for reporting these issues. Upstream acknowledges Jon Larimer of IBM X-Force as the original reporter of these issues.
Users are advised to upgrade to these updated packages, which contain a backported patch to correct these issues.
