Description
==========
Tavis Ormandy of the Gentoo Linux Security Audit Team identified a flaw
in the handling of image filenames by xv.

Successful exploitation would require a victim to process a specially
crafted image with a malformed filename, potentially resulting in the
execution of arbitrary code.

Workaround

All xv users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/xv-3.10a-r10"
