(XV: Multiple vulnerabilities)

    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.
  
Workaround :

    There is no known workaround at this time."
