Insight
Insight
Multiple vulnerabilities has been found and corrected in libpng: Memory leak in the png_handle_tEXt function in pngrutil.c in libpng before 1.2.33 rc02 and 1.4.0 beta36 allows context-dependent attackers to cause a denial of service (memory exhaustion) via a crafted PNG file (CVE-2008-6218. Buffer overflow in pngpread.c in libpng before 1.2.44 and 1.4.x before 1.4.3, as used in progressive applications, might allow remote attackers to execute arbitrary code via a PNG image that triggers an additional data row (CVE-2010-1205). Memory leak in pngrutil.c in libpng before 1.2.44, and 1.4.x before 1.4.3, allows remote attackers to cause a denial of service (memory consumption and application crash) via a PNG image containing malformed Physical Scale (aka sCAL) chunks (CVE-2010-2249). As a precaution htmldoc has been rebuilt to link against the system libpng library for CS4 and 2008.0. Latest xulrunner and mozilla-thunderbird has been patched as a precaution for 2008.0 wheres on 2009.0 and up the the system libpng library is used instead of the bundled copy. htmldoc, xulrunner and mozilla-thunderbird packages is therefore also being provided with this advisory. Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program.
