Adobe Shockwave TextXtra Invalid Seek Remote Code Execution VulnerabilityTPTI-11-02: February 8th, 2011
Vulnerability DetailsThis vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Shockwave. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the code responsible for parsing a DEMX RIFF chunk within Director files. The logic within the TextXtra.x32 module fails to account for a specific condition and can be made to misallocate a buffer on the heap. By crafting specific values within DEMX substructures an attacker can corrupt memory leading to arbitrary code execution under the context of the user running the browser.
