Description:
Secunia Research has discovered some vulnerabilities in ZipGenius, which can be exploited by malicious people to compromise a user's system.

1) A boundary error exists in "zipgenius.exe", "zg.exe", "zgtips.dll", and "contmenu.dll" when reading the filename of a compressed file from a ZIP archive. This can be exploited to cause a stack-based buffer overflow when a malicious archive containing a file with an overly long filename is read either in ZipGenius or from Windows Explorer.

2) A boundary error exists in "zipgenius.exe" when handling the original name of a UUE/XXE/MIM encoded file. This can be exploited to cause a stack-based buffer overflow when a malicious UUE/XXE/MIM archive containing an encoded file with an overly long filename is opened.

3) A boundary error exists in "unacev2.dll" when extracting an ACE archive containing a file with an overly long filename. This can be exploited to cause a stack-based buffer overflow when a malicious ACE archive is extracted using "zipgenius.exe" or "zg.exe".

Vulnerability #3 is related to:
SA14359

The vulnerabilities have been confirmed in version 5.5.1.468 and 6.0.2.1041. Prior versions may also be affected.
