|Gentoo Linux Security Advisory
Title: XV: Multiple vulnerabilities (GLSA 200504-17)
Date: April 19, 2005
Multiple vulnerabilities have been discovered in XV, potentially resulting in the execution of arbitrary code.
XV is an interactive image manipulation program for the X Window System.
Vulnerable: < 3.10a-r11
Unaffected: >= 3.10a-r11
Architectures: All supported architectures
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.
Successful exploitation would require a victim to view a specially created image file using XV, potentially resulting in the execution of arbitrary code.
There is no known workaround at this time.
All XV users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/xv-3.10a-r11"
