DESCRIPTION:
Secunia Research has discovered a vulnerability in ALZip, which can
be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to multiple boundary errors when
reading the filename of a compressed file from ALZ, ARJ, ZIP, UUE, or
XXE archives. This can be exploited to cause a stack-based buffer
overflow (ALZ), or a heap-based buffer overflow (ARJ / ZIP / UUE /
XXE).
Successful exploitation allows execution of arbitrary code when a
malicious ALZ / ARJ archive is opened, or when a ZIP / UUE / XXE
archive is extracted.
The vulnerability has been confirmed in the following versions:
* ALZip v6.12 (Korean)
* ALZip v6.1 (International)
* ALZip v5.52 (English)
Prior versions may also be affected.
SOLUTION:
Update to version 6.13 (Korean and International).
