From bugzilla@redhat.com Thu Feb 5 22:56:44 2004 From: bugzilla@redhat.com To: redhat-watch-list@redhat.com, bugtraq@securityfocus.com, full-disclosure@lists.netsys.com Date: Thu, 5 Feb 2004 03:51 -0500 Subject: [Full-Disclosure] [RHSA-2004:030-01] Updated NetPBM packages fix multiple temporary file vulnerabilities -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated NetPBM packages fix multiple temporary file vulnerabilities Advisory ID: RHSA-2004:030-01 Issue date: 2004-02-05 Updated on: 2004-02-05 Product: Red Hat Linux Keywords: symlink tmpfile tmp Cross references: Obsoletes: CVE Names: CAN-2003-0924 - --------------------------------------------------------------------- 1. Topic: Updated NetPBM packages are available that fix a number of temporary file vulnerabilities in the netpbm libraries. 2. Relevant releases/architectures: Red Hat Linux 9 - 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. A number of temporary file bugs have been found in versions of NetPBM. These could allow a local user the ability to overwrite or create files as a different user who happens to run one of the the vulnerable utilities. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0924 to this issue. Users are advised to upgrade to the erratum packages, which contain patches from Debian that correct these bugs. 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. If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website: https://rhn.redhat.com/help/latest-up2date.pxt 5.
