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.
