Severity: Normal Title: FreeType: Multiple vulnerabilities Date: May 24, 2009 Bugs: #263032 ID: 200905-05


Synopsis

Multiple integer overflows in FreeType might allow for the remote execution of arbitrary code or a Denial of Service.

Background

FreeType is a high-quality and portable font engine.

Affected packages

-------------------------------------------------------------------
 Package              /  Vulnerable  /                  Unaffected
-------------------------------------------------------------------

1 media-libs/freetype < 2.3.9-r1 >= 2.3.9-r1

Description

Tavis Ormandy reported multiple integer overflows in the cff_charset_compute_cids() function in cff/cffload.c, sfnt/tccmap.c and the ft_smooth_render_generic() function in smooth/ftsmooth.c, possibly leading to heap or stack-based buffer overflows.

Impact

A remote attacker could entice a user or automated system to open a specially crafted font file, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All FreeType users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/freetype-2.3.9-r1&quot;
