TITLE:
NOD32 Anti-Virus ARJ Archive Handling Buffer Overflow

SECUNIA ADVISORY ID:
SA16604

VERIFY ADVISORY:
http://secunia.com/advisories/16604/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
NOD32 for Windows NT/2000/XP 2.x
http://secunia.com/product/1066/

DESCRIPTION:
Secunia research has discovered a vulnerability in NOD32 Anti-Virus,
which potentially can be exploited by malicious people to compromise
a vulnerable system.

The vulnerability is caused due to an error in handling ARJ archives
containing compressed files with overly long filename. This can be
exploited to cause a heap-based buffer overflow when a specially
crafted ARJ archive is scanned.

Successful exploitation may allow arbitrary code execution, but
requires that archive scanning is enabled.

The vulnerability has been confirmed in NOD32 for Windows
NT/2000/2003/XP Trial Version 2.5 (with nod32.002 version 1.033 build
1127). Other versions may also be affected.

SOLUTION:
Update to the latest version (nod32.002 version 1.034 build 1132) via
online update.

PROVIDED AND/OR DISCOVERED BY:
