Security Advisory - RHSA-2003:060-09
------------------------------------------------------------------------------
Summary:
Updated NetPBM packages fix multiple vulnerabilities
Updated NetPBM packages are available that fix a number of vulnerabilities
in the netpbm libraries.
Description:
The netpbm package contains a library of functions that support
programs for handling various graphics file formats, including .pbm
(portable bitmaps), .pgm (portable graymaps), .pnm (portable anymaps),
.ppm (portable pixmaps), and others.
During an audit of the NetPBM library, Al Viro, Alan Cox, and Sebastian
Krahmer found a number of bugs that are potentially exploitable. These
bugs could be exploited by creating a carefully crafted image in such a way
that it executes arbitrary code when it is processed by either an
application from the netpbm-progs package or an application that uses the
vulnerable netpbm library.
One way that an attacker could exploit these vulnerabilities would be to
submit a carefully crafted image to be printed, as the LPRng print spooler
used by default in Red Hat Linux releases uses netpbm utilities to parse
various types of image files.
Users are advised to upgrade to the erratum packages, which contain patches
that correct these vulnerabilities.
