New XV image viewer packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, and -current to fix security issues. Format string and other issues could cause a crash or execution of arbitrary code if a specially crafted image is loaded with XV.



Here are the details from the Slackware 10.1 ChangeLog:
+--------------------------+
patches/packages/xv-3.10a-i486-4.tgz: Upgraded to the latest XV jumbo
patches, xv-3.10a-jumbo-fix-patch-20050410 and
xv-3.10a-jumbo-enh-patch-20050501. These fix a number of format string
and other possible security issues in addition to providing many other
bugfixes and enhancements.
(Thanks to Greg Roelofs)
