Service

SA39736

VERIFY ADVISORY:
http://secunia.com/advisories/39736/

DESCRIPTION:
Oleksiuk Dmitry has discovered a vulnerability in ESET Smart Security
and ESET NOD32 Antivirus, which can be exploited by malicious people
to cause a DoS (Denial of Service).

The vulnerability is caused due to an error when processing LZH
archives. This can be exploited to hang an affected system when a
specially crafted LZH archive is scanned.

The vulnerability is confirmed in ESET Smart Security version
4.2.40.0 and ESET NOD32 Antivirus version 4.2.42.0. Other versions
may also be affected.

SOLUTION:
Do not scan LZH archives using the application. Restrict local access
to trusted users only.
