Description


Two vulnerabilities have been reported in various Symantec products, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.

1) A boundary error in Symantec's Decomposer engine can be exploited to cause a stack-based buffer overflow when handling a specially crafted .RAR file.

Successful exploitation allows execution of arbitrary code.

2) An error in Symantec's Decomposer engine can be exploited to cause the process to consume large amounts of memory when handling a specially crafted .RAR file.
