|Gentoo Linux Security Advisory
Title: FreeType: Buffer overflow (GLSA 200705-22)
Date: May 30, 2007
A vulnerability has been discovered in FreeType allowing for the execution of arbitrary code.
FreeType is a True Type Font rendering library.
Vulnerable: < 2.3.4-r2
Unaffected: >= 2.3.4-r2
Unaffected: < 2.0
Architectures: All supported architectures
Victor Stinner discovered a heap-based buffer overflow in the function Get_VMetrics() in src/truetype/ttgload.c when processing TTF files with a negative n_points attribute.
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.
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-2.3.4-r2"
