Synopsis

Multiple vulnerabilities have been discovered in XV, potentially resulting in the execution of arbitrary code.

2. Impact Information

Background

XV is an interactive image manipulation program for the X Window System.

Description

Greg Roelofs has reported multiple input validation errors in XV image decoders. Tavis Ormandy of the Gentoo Linux Security Audit Team has reported insufficient validation in the PDS (Planetary Data System) image decoder, format string vulnerabilities in the TIFF and PDS decoders, and insufficient protection from shell meta-characters in malformed filenames.

Impact

Successful exploitation would require a victim to view a specially created image file using XV, potentially resulting in the execution of arbitrary code.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All XV users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/xv-3.10a-r11"
