Debian DSA-2335-1 : man2html - missing input sanitization

medium Nessus Plugin ID 56715

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Tim Starling discovered that the Debian-native CGI wrapper for man2html, a program to convert UNIX man pages to HTML, is not properly escaping user-supplied input when displaying various error messages. A remote attacker can exploit this flaw to conduct cross-site scripting (XSS) attacks.

Solution

Upgrade the man2html packages.

For the oldstable distribution (lenny), this problem has been fixed in version 1.6f-3+lenny1.

For the stable distribution (squeeze), this problem has been fixed in version 1.6f+repack-1+squeeze1.
