Title: FreeType: Multiple vulnerabilities (GLSA 200905-05)
Date: May 24, 2009
Updated: May 25, 2009
Multiple integer overflows in FreeType might allow for the remote execution of arbitrary code or a Denial of Service.
FreeType is a high-quality and portable font engine.
Vulnerable: < 2.3.9-r1
Unaffected: >= 2.3.9-r1
Unaffected: < 2.0
Architectures: All supported architectures
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.
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.
There is no known workaround at this time.
All FreeType users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/freetype-2.3.9-r1"
