(RHSA-2011:0009) Moderate: evince security update

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.
