System access

This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user.

Tielei Wang has discovered a vulnerability in Adobe Flash Professional CS5, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an integer overflow error in Flash.exe when allocating memory to process a JPG object using its image dimensions. This can be exploited to cause a heap-based buffer overflow via a specially crafted FLA file.

Successful exploitation may allow execution of arbitrary code, but requires tricking a user into opening a malicious file.

The vulnerability is reported in version 11.5.1.349 and prior for Windows and Macintosh (confirmed in 11.5.1.349).

Update to version 11.5.2 or upgrade to Adobe Flash Professional CS6.
