Path Traversal Vulnerability in IZArc's unrar.dll

An issue in the unrar.dll component of IZArc v4.6 allows attackers to execute a path traversal.

In IZArc through 4.5, there is a Mark-of-the-Web Bypass Vulnerability. When a user performs an extraction from an archive file that bears Mark-of-the-Web, Mark-of-the-Web is not propagated to the extracted files. NOTE: this is disputed because Mark-of-the-Web propagation can increase risk via security-warning habituation, and because the intended control sphere for file-origin metadata (e.g., HostUrl in Zone.Identifier) may be narrower than that for reading the file's content.

IZArc 4.1.8 displays a file's name on the basis of a ZIP archive's Central Directory entry, but launches this file on the basis of a ZIP archive's local file header, which allows user-assisted remote attackers to conduct file-extension spoofing attacks via a modified Central Directory, as demonstrated by unintended code execution prompted by a .jpg extension in the Central Directory and a .exe extension in the local file header.

Untrusted search path vulnerability in IZArc Archiver 4.1.2 allows local users to gain privileges via a Trojan horse ztv7z.dll file in the current working directory, as demonstrated by a directory that contains a .arj file. NOTE: some of these details are obtained from third party information.
