Posted on: 01/24/2005 10:44 AM

An enscript security update has been released for Ubuntu Linux 4.10

===========================================================
Ubuntu Security Notice USN-68-1 January 24, 2005
enscript vulnerabilities
CAN-2004-1184 CAN-2004-1185 CAN-2004-1186
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

enscript

The problem can be corrected by upgrading the affected package to version 1.6.4-4ubuntu0.1. In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

Erik Sjlund discovered several vulnerabilities in enscript which could cause arbitrary code execution with the privileges of the user calling enscript.

Quotes and other shell escape characters in titles and file names were not handled in previous versions. (CAN-2004-1184)

Previous versions supported reading EPS data not only from a file, but also from an arbitrary command pipe. Since checking for unwanted side effects is infeasible, this feature has been disabled after consultation with the authors of enscript. (CAN-2004-1185)

Finally, this update fixes two buffer overflows which were triggered by certain input files. (CAN-2004-1186)

These issues can lead to privilege escalation if enscript is called automatically from web server applications like viewcvs.
