Detail

Synopsis

Multiple vulnerabilities in FreeType might result in the remote execution of arbitrary code.

Background

FreeType is a True Type Font rendering library.

Description

Multiple issues found in FreeType 2 were also discovered in FreeType 1.
For details on these issues, please review the Gentoo Linux Security Advisories and CVE identifiers referenced below.

Impact

A remote attacker could entice a user to open a specially crafted TTF file, possibly resulting in the execution of arbitrary code with the privileges of the user running FreeType.

Workaround

There is no known workaround at this time.

Resolution

All FreeType 1 users should upgrade to an unaffected version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/freetype-1.4_pre20080316-r2"

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since May 27, 2009. It is likely that your system is already no longer affected by this issue.
