Red Hat Security Advisory Synopsis: Updated Net-SNMP packages fix security and other bugs Advisory ID: RHSA-2002:228-11 Issue date: 2002-10-09 Updated on: 2002-12-17 Product: Red Hat Linux Keywords: ucd-snmp flaw:design Cross references: Obsoletes: CVE Names: CAN-2002-1170 --------------------------------------------------------------------- 1. Topic: The Net-SNMP packages shipped with Red Hat Linux 8.0 contain several bugs including a remote denial of service vulnerability. This errata release corrects those problems. 2. Relevant releases/architectures: Red Hat Linux 8.0 - i386 3. Problem description: The Net-SNMP project includes various Simple Network Management Protocol (SNMP) tools. The SNMP daemon included in the Net-SNMP package versions 5.0.1 through 5.0.4 can be caused to crash if it is sent a specially crafted packet. Successful exploitation of this issue would require knowledge of a known SNMP community string. Red Hat Linux 8.0 shipped with Net-SNMP 5.0.1 and is therefore vulnerable to this issue. Users of Net-SNMP should upgrade to these errata packages containing Net-SNMP 5.0.6 which is not vulnerable to this issue. In addition, Net-SNMP 5.0.6 fixes a number of other minor 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. 5.
