TITLE:

SECUNIA ADVISORY ID:
SA20179

VERIFY ADVISORY:
http://secunia.com/advisories/20179/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
ZipCentral 4.x
http://secunia.com/product/9233/

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

The vulnerability is caused due to a boundary error within the
handling of filenames in a ZIP archive. This can be exploited to
cause a stack-based buffer overflow when a malicious ZIP archive
containing a file with an overly long filename is extracted.

Successful exploitation allows arbitrary code execution.

The vulnerability has been confirmed in version 4.01. Other versions
may also be affected.

SOLUTION:
Do not extract ZIP files from untrusted sources.
