FreeType is a font rendering library for TrueType Font (TTF) and
Printer Font Binary (PFB).
Regenrecht reported multiple vulnerabilities in FreeType via iDefense:
An integer overflow when parsing values in the Private dictionary table
in a PFB file, leading to a heap-based buffer overflow
An invalid free() call related to parsing an invalid "number of axes"
field in a PFB file (CVE-2008-1807).
Multiple off-by-one errors when parsing PBF and TTF files, leading to
heap-based buffer overflows (CVE-2008-1808).
<impact type="normal">
A remote attacker could entice a user to open a specially crafted TTF
or PBF file, possibly resulting in the execution of arbitrary code with
the privileges of the user running an application linked against
FreeType (such as the X server, running as root).
There is no known workaround at this time.
All FreeType users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/freetype-2.3.6&quot;</code>
