Red Hat Security Advisory Synopsis: Updated Ethereal packages are available Advisory ID: RHSA-2002:290-07 Issue date: 2003-01-09 Updated on: 2003-01-08 Product: Red Hat Linux Keywords: ethereal dissector PPP LMP TDS BGP Cross references: Obsoletes: RHSA-2002:169 CVE Names: CAN-2002-1355 CAN-2002-1356 --------------------------------------------------------------------- 1. Topic: Updated Ethereal packages are available which fix various security issues. 2. Relevant releases/architectures: Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 3. Problem description: Ethereal is a package designed for monitoring network traffic on your system. Several security issues have been found in the Ethereal packages distributed with Red Hat Linux versions 7.2, 7.3, and 8.0 Multiple integer signedness errors in the BGP dissector in Ethereal 0.9.7 and earlier allow remote attackers to cause a denial of service (infinite loop) via malformed messages. This problem was discovered by Silvio Cesare. CAN-2002-1355 Ethereal 0.9.7 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via malformed packets to the LMP, PPP, or TDS dissectors. CAN-2002-1356 Users of Ethereal should update to the erratum packages containing Ethereal version 0.9.8 which is not vulnerable to these issues. 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.
