The ActionScript 2 virtual machine in Adobe Flash Player 10.x before 10.0.12.36 and 9.x before 9.0.151.0, and Adobe AIR before 1.5, does not validate character elements during retrieval from the dictionary data structure, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted PDF file.

Security readout for executives and security teams

CVE-2008-5363 is a crash vulnerability in older Adobe Flash Player and Adobe AIR versions. A malicious PDF could trigger a NULL pointer dereference in the ActionScript 2 virtual machine, causing the application to crash. The provided sources describe denial of service, not code execution. Exposure is limited to environments still running the listed legacy Adobe Flash Player or Adobe AIR versions and opening attacker-controlled PDF content. Modern exposure cannot be inferred from the supplied sources. Treat this as a legacy-technology risk. It is not evidenced as actively exploited in the supplied sources, but any remaining affected Flash or AIR deployment should be removed from production exposure or updated. Mitigation focus: Upgrade Flash Player to 10.0.12.36 or 9.0.151.0 or later where still applicable.; Upgrade Adobe AIR to 1.5 or later where still applicable.; Restrict untrusted PDF handling on systems that retain affected Adobe components..
