Conectiva Linux Advisory: netpbm

May 28, 2003, 14:58 (0 Talkback[s])

CONECTIVA LINUX SECURITY ANNOUNCEMENT
PACKAGE : netpbm
SUMMARY : Multiple vulnerabilities
DATE : 2003-05-27 14:54:00
ID : CLA-2003:656
RELEVANT
RELEASES
: 8

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.
