Winzip Unspecified Multiple Buffer Overflow Vulnerabilities

Secunia ID	SA12430
Release Date	02 Sep 2004
Last Change	08 Jan 2007
Criticality	Highly Critical Typically used for remotely exploitable vulnerabilities that can lead to system compromise. Successful exploitation does not normally require any interaction but there are no known exploits available at the time of disclosure. Such vulnerabilities can exist in services like FTP, HTTP, and SMTP or in client systems like email programs or browsers.
Solution Status	Vendor Patch
Software	WinZip 3.x WinZip 6.x WinZip 7.x WinZip 8.x WinZip 9.x
Where	From remote "From remote" describes other vulnerabilities where the attack vector doesn't require access to the system or a local network. This category covers services that are acceptable to expose to the Internet (e.g. HTTP, HTTPS, SMTP). It also covers client applications used on the Internet and certain vulnerabilities where it is reasonable to assume that a security conscious user can be tricked into performing certain actions.
Impact	System access This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user.
Description	Multiple vulnerabilities has been reported in Winzip, which potentially can be exploited to compromise a user's system. 1) Some unspecified vulnerabilities, which can be exploited to cause buffer overflows. Successful exploitation can potentially lead to execution of arbitrary code. 2) A problem caused due to insufficient validation of command-line arguments. This can be exploited by using a specially crafted argument to cause a buffer overflow and potentially execute arbitrary code.
Solution	Update to 9.0 SR-1: http://www.winzip.com/dprob.htm
Reported by	Reported by vendor.
