WinZip 7Z File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of WinZip. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of 7Z files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24986.

WinZip Mark-of-the-Web Bypass Vulnerability. This vulnerability allows remote attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of WinZip. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of archive files. When opening an archive that bears the Mark-of-the-Web, WinZip removes the Mark-of-the-Web from the archive file. Following extraction, the extracted files also lack the Mark-of-the-Web. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current user. Was ZDI-CAN-23983.

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 Winzip32.exe in WinZip 9.0 allows local users to cause a denial of service (application crash) and possibly execute arbitrary code via a long command line argument. NOTE: this issue may cross privilege boundaries if an application automatically invokes Winzip32.exe for untrusted input filenames, as in the case of a file upload application. NOTE: The provenance of this information is unknown; the details are obtained solely from third party information.

Buffer overflow in the WZFILEVIEW.FileViewCtrl.61 ActiveX control (aka Sky Software "FileView" ActiveX control) for WinZip 10.0 Build 6667 allows remote attackers to execute arbitrary code via a long argument to the CreateNewFolderFromName method, a different vulnerability than CVE-2006-5198.

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.

The WZFILEVIEW.FileViewCtrl.61 ActiveX control (aka Sky Software "FileView" ActiveX control) for WinZip 10.0 before build 7245 allows remote attackers to execute arbitrary code via unspecified "unsafe methods."

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.

Multiple stack-based buffer overflows in the get_header function in header.c for LHA 1.14, as used in products such as Barracuda Spam Firewall, allow remote attackers or local users to execute arbitrary code via long directory or file names in an LHA archive, which triggers the overflow when testing or extracting the archive.

Multiple directory traversal vulnerabilities in LHA 1.14 allow remote attackers or local users to create arbitrary files via an LHA archive containing filenames with (1) .. sequences or (2) absolute pathnames with double leading slashes ("//absolute/path").

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.

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.

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.
