"Several vulnerabilities have been discovered in xli, an image viewer
for X11. The Common Vulnerabilities and Exposures project identifies
the following problems :

  - CAN-2001-0775
    A buffer overflow in the decoder for FACES format images
    could be exploited by an attacker to execute arbitrary
    code. This problem has already been fixed in xloadimage
    in DSA 069.

  - CAN-2005-0638

    Tavis Ormandy of the Gentoo Linux Security Audit Team
    has reported a flaw in the handling of compressed
    images, where shell meta-characters are not adequately
    escaped.

  - CAN-2005-0639

    Insufficient validation of image properties in have been
    discovered which could potentially result in buffer
    management errors."
