Multiple Vulnerabilities Discovered in Adobe Flash Player and Adobe AIR (APSB14-09)
Multiple vulnerabilities have been discovered in Adobe Flash Player and Adobe AIR. Adobe Flash Player is a widely distributed multimedia and application player used to enhance the user experience when visiting web pages or reading email messages. Adobe AIR is a cross platform runtime used for developing internet applications that run outside of a browser. Successful exploitation could result in an attacker compromising data security, potentially allowing access to confidential data, or could compromise processing resources in a user's computer. Failed exploit attempts will likely cause denial-of-service conditions.
At this time these vulnerabilities are not publicly disclosed and there is no known proof-of-concept code available.
- Adobe Flash Player 126.96.36.199 and earlier versions for Windows and Macintosh
- Adobe Flash Player 188.8.131.526 and earlier versions for Linux
