VERIFY ADVISORY:
http://secunia.com/advisories/17251/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
WinAce 2.x
http://secunia.com/product/4231/

DESCRIPTION:
Secunia Research has discovered a vulnerability in WinACE, which can
be exploited by malicious people to compromise a user's system. 

The vulnerability is caused due to a boundary error when reading an
overly large ARJ header block into a fixed-sized heap buffer. This
can be exploited to cause a heap-based buffer overflow.

Successful exploitation allows execution of arbitrary code when a
malicious ARJ archive is opened.

The vulnerability has been confirmed in version 2.60. Prior versions
may also be affected.

SOLUTION:
The vulnerability will be fixed in version 2.61.

Don't open untrusted ARJ archives.
