Technical description

Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, allows remote attackers to execute arbitrary code via a crafted JPC_MS_RGN marker in the Jp2c stream of a JpxDecode encoded data stream, which triggers an integer sign extension that bypasses a sanity check, leading to memory corruption.

Remediation

Check the references section for vendor advisories and patches from adobe. Update acrobat to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
