Description:
Ryan Smith has reported a vulnerability in avast!, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the anti-virus engine when processing LHA archives. This can be exploited to cause a heap-based buffer overflow via a specially crafted LHA archive with overly long filename and directory name extended-header fields.
Successful exploitation allows execution of arbitrary code.
The vulnerability is reported in the anti-virus engine prior to versions 4.7.869 for desktops and 4.7.660 for servers.
