TITLE

Apple QuickDraw Manager heap buffer overflow vulnerability

DESCRIPTION

The InternalUnpackBits function in Apple QuickDraw, as used by Quicktime 7.1.3 and other applications on Mac OS X 10.4.8 and earlier, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted PICT file that triggers memory corruption in the _GetSrcBits32ARGB function. NOTE: this issue might overlap CVE-2007-0462. Apple QuickDraw contains a heap buffer overflow vulnerability. This vulnerability may allow an attacker to execute arbitrary code or create a denial-of-service condition. Quicktime Used in etc. Mac OS X QuickDraw is prone to a remote memory-corruption vulnerability because the software fails to properly handle malformed PICT image files. Successfully exploiting this issue allows remote attackers to corrupt memory and to crash the affected software. Mac OS X 10.4.8 is vulnerable to this issue; other versions are also likely affected, since the vulnerable component has been included in Apple operating systems since System 6.0.4. QuickDraw is a graphics processing tool bundled in the Apple operating system. A memory corruption vulnerability exists in QuickDraw when parsing PICT graphics with malformed ARGB records. Remote attackers may exploit this vulnerability to perform denial of service attacks on user machines. If the user is tricked into opening a malicious graphics file, this vulnerability will be triggered, destroying the pointer sent to the _GetSrcBits32ARGB function, resulting in a denial of service. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German. The improvements will help our customers to get a better understanding of how we reached our conclusions, how it was rated, our thoughts on exploitation, attack vectors, and scenarios.

The vulnerability is caused due to an error in the fatfile_getarch2() function. This can be exploited to cause an integer overflow and may potentially allow execution of arbitrary code with kernel privileges via a specially crafted Mach-O Universal binary. The vulnerability is reported in a fully patched Mac OS X (2006-11-26). Other versions may also be affected. SOLUTION: Grant only trusted users access to affected systems.
