Conectiva Linux Advisory: netpbm

CONECTIVA LINUX SECURITY ANNOUNCEMENT

DESCRIPTION

The netpbm package contains a library of functions and a set of
basic tools to manipulate various graphics file formats, including
pbm, pgm, pnm, ppm and others.

Alan Cox and Al Viro discovered[1] several “math overflow”
vulnerabilities in netpbm versions <= 9.20. These
vulnerabilities can be exploited by attackers using specially
crafted images. Successful exploitation can lead to denial of
service conditions or arbitrary code execution with the privileges
of the user running the affected program.

The netpbm packages included in this update announcement are
based on netpbm version 9.20 and contain a patch to fix the
aforementioned vulnerabilities.

The Common Vulnerabilities and Exposures (CVE) project has
assigned the name CAN-2003-0146 to this issue[2].

SOLUTION

All netpbm users should upgrade.
