  <title>xli, xloadimage: Multiple vulnerabilities</title>
  <synopsis>
    xli and xloadimage are vulnerable to multiple issues, potentially leading
    to the execution of arbitrary code.

    <p>
    xli and xloadimage are X11 utilities for displaying and manipulating a
    wide range of image formats.
    </p>

  <description>
    <p>
    Tavis Ormandy of the Gentoo Linux Security Audit Team has reported that
    xli and xloadimage contain a flaw in the handling of compressed images,
    where shell meta-characters are not adequately escaped. Rob Holland of
    the Gentoo Linux Security Audit Team has reported that an xloadimage
    vulnerability in the handling of Faces Project images discovered by
    zen-parse in 2001 remained unpatched in xli. Additionally, it has been
    reported that insufficient validation of image properties in xli could
    potentially result in buffer management errors.
    </p>
  </description>
  <impact type="normal">
    <p>
    Successful exploitation would permit a remote attacker to execute
    arbitrary shell commands, or arbitrary code with the privileges of the
    xloadimage or xli user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All xli users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-gfx/xli-1.17.0-r1"</code>
    <p>
    All xloadimage users should also upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-gfx/xloadimage-4.1-r2"</code>
  </resolution>
