CentOS Errata and Security Advisory CESA-2005:743
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.
A bug was found in the way netpbm converts PostScript files into PBM, PGM or PPM files. An attacker could create a carefully crafted PostScript file in such a way that it could execute arbitrary commands when the file is processed by a victim using pstopnm. The Common Vulnerabilities and Exposures project assigned the name CAN-2005-2471 to this issue.
All users of netpbm should upgrade to the updated packages, which contain a backported patch to resolve this issue.
