RHSA-2003-061: netpbm

Vulnerability Assessment Summary Check for the version of the netpbm packages Detailed Explanation for this Vulnerability Assessment Updated NetPBM packages are available that fix a number of vulnerabilities in the netpbm libraries. 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 a possible hacker 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 Advanced Products releases uses netpbm utilities to parse various types of image files. Users are advised to upgrade to the updated packages, which contain patches that correct these vulnerabilities.
