TITLE: ZipCentral ZIP File Handling Buffer Overflow Vulnerability
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.
