HTTP: Adobe Shockwave Director tSAC Chunk Parsing Memory Corruption

This signature detects attempts to exploit a known code execution vulnerability in Adobe Shockwave player. It is due to a signedness error while parsing tSAC chunks in Adobe Director files. By providing a certain negative value, calculation of a pointer can lead to a memory corruption. Remote attackers can exploit this by enticing target users to open a malicious DIR file using a vulnerable version of the product. A successful attack can result in arbitrary code execution in the security context of the logged in user. In an unsuccessful attack, the affected application can terminate abnormally.
