Description:

Security updates are released for Adobe Flash Player to address multiple vulnerabilities caused by type confusion, various buffer overflow, use-after-free error, memory leak and memory corruption. To successfully exploit the vulnerabilities, a remote attacker could entice a targeted user to open a specially crafted web page, Flash file, or document that supports embedded Flash content.

Affected Systems:

• Adobe Flash Player for Windows and Macintosh 18.0.0.232 and earlier versions
• Adobe Flash Player for Google Chrome 18.0.0.233 and earlier versions
• Adobe Flash Player for Linux 11.2.202.508 and earlier versions
• AIR Desktop Runtime, SDK 18.0.0.199 and earlier versions
• AIR SDK & Complier 18.0.0.180 and earlier versions
• AIR for Android 18.0.0.143 and earlier versions

Impact:

A successful attack could lead to arbitrary code execution, information disclosure, bypass of security restrictions or potentially take control of the affected system.
