WinZip 8.0 uses weak random number generation for password protected ZIP files, which allows local users to brute force the encryption keys and extract the data from the zip file by guessing the state of the stream coder.

Stack-based buffer overflow in the Sky Software FileView ActiveX control, as used in WinZip 10 before build 7245 and in certain other applications, allows remote attackers to execute arbitrary code via a long FilePattern attribute in a WZFILEVIEW object, a different vulnerability than CVE-2006-5198.

WinZip before 11.0 does not properly verify the authenticity of updates, which allows man-in-the-middle attackers to execute arbitrary code via a Trojan horse update, as demonstrated by evilgrade and DNS cache poisoning.

Buffer overflow in WinZip 8.0 allows attackers to execute arbitrary commands via a long file name that is processed by the /zipandemail command line option.

Multiple buffer overflows in WinZip 9.0 and earlier may allow attackers to execute arbitrary code via multiple vectors, including the command line.

Buffer overflow in the UUDeview package, as used in WinZip 6.2 through WinZip 8.1 SR-1, and possibly other packages, allows remote attackers to execute arbitrary code via a MIME archive with certain long MIME parameters.
