Filzip unacev2.dll ACE archive buffer overflow

filzip-unacev2-bo (26447) The risk level is classified as HighHigh Risk

Description:

Filzip is vulnerable to a stack-based buffer overflow caused by improper bounds checking of file names by the UNACEV2.DLL file. By creating a malicious ACE archive containing an overly long file name, a remote attacker could overflow a buffer and execute arbitrary code on the system, once the malicious ACE file is extracted.

Platforms Affected:

  • Philipp Engel, Filzip 3.04

Remedy:

Upgrade to the latest versions of Filzip, available from the Filzip Web site. See References.
