--------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated NetPBM packages fix multiple vulnerabilities Advisory ID: RHSA-2003:060-01 Issue date: 2003-04-03 Updated on: 2003-04-03 Product: Red Hat Linux Keywords: Cross references: RHSA-2002:048 Obsoletes: CVE Names: CAN-2003-0146 --------------------------------------------------------------------- 1. Topic: Updated NetPBM packages are available that fix a number of vulnerabilities in the netpbm libraries. 2. Relevant releases/architectures: Red Hat Linux 7.0 - i386 Red Hat Linux 7.1 - i386 Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 3. Problem 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5.
