Description:
ISS X-Force has reported a vulnerability in multiple Symantec products, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the DEC2EXE parsing engine used by the antivirus scanning functionality when processing UPX compressed files. This can be exploited to cause a heap-based buffer overflow via a specially crafted UPX file.

Successful exploitation allows execution of arbitrary code.
