Description


Kaveh Ghaemmaghami has discovered two vulnerabilities in Corel PDF Fusion, which can be exploited by malicious people to compromise a user's system.

1) The application loads a library (wintab32.dll) in an insecure manner. This can be exploited to load arbitrary libraries by tricking a user into e.g. opening a ".pdf" or ".xps" file located on a remote WebDAV or SMB share.

2) A boundary error exists when parsing names in ZIP directory entries of a XPS file and can be exploited to cause a stack-based buffer overflow by tricking a user into opening a specially crafted XPS file.

Successful exploitation of the vulnerabilities allows execution of arbitrary code.

The vulnerabilities are confirmed in version 1.11. Other versions may also be affected.
