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.

* Symantec AntiVirus for Network Attached Storage version 4.3.16.39
and prior
