Description:
Secunia Research has discovered a vulnerability in AVIRA Desktop for Windows antivirus, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error when reading the filename of a compressed file from an ACE archive. This can be exploited to cause a stack-based buffer overflow when an ACE archive containing a compressed file with an overly long filename is scanned.
Successful exploitation allows arbitrary code execution, but requires that archive scanning is enabled.
The vulnerability has been confirmed in version 1.00.00.68 with AVPACK32.DLL version 6.31.0.3.
The vulnerability is related to:
SA14359
Solution:
Update to the latest version via online update. (AVPACK32.DLL version 6.31.1.7).
Provided and/or discovered by:
