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.

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.

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.

Buffer overflow in the ZIP capability for multiple products allows remote attackers to cause a denial of service or execute arbitrary code via ZIP files containing entries with long filenames, including (1) Microsoft Windows 98 with Plus! Pack, (2) Windows XP, (3) Windows ME, (4) Lotus Notes R4 through R6 (pre-gold), (5) Verity KeyView, and (6) Stuffit Expander before 7.0.
