Severity: Normal Title: FreeType: User-assisted execution of arbitrary code Date: June 23, 2008 Bugs: #225851 ID: 200806-10

Synopsis ========
Font parsing vulnerabilities in FreeType might lead to user-assisted execution of arbitrary code.
Background ==========
FreeType is a font rendering library for TrueType Font (TTF) and Printer Font Binary (PFB).
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/freetype < 2.3.6 >= 2.3.6
Description ===========
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 (CVE-2008-1806).
* 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 ======
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.org X server, running as root).
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 ">=media-libs/freetype-2.3.6"
