--------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated sendmail packages fix vulnerability Advisory ID: RHSA-2003:120-01 Issue date: 2003-03-31 Updated on: 2003-03-31 Product: Red Hat Linux Keywords: sendmail Cross references: Obsoletes: RHSA-2003:073 CVE Names: CAN-2003-0161 --------------------------------------------------------------------- 1. Topic: Updated Sendmail packages are available to fix a vulnerability that allows local and possibly remote attackers to gain root privileges. 2. Relevant releases/architectures: Red Hat Linux 6.2 - i386 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 Red Hat Linux 9 - i386 3. Problem description: Sendmail is a widely used Mail Transport Agent (MTA) which is included in all Red Hat Linux distributions. There is a vulnerability in Sendmail versions prior to and including 8.12.8. The address parser performs insufficient bounds checking in certain conditions due to a char to int conversion, making it possible for an attacker to take control of the application. Although no exploit currently exists, this issue is probably locally exploitable and may also be remotely exploitable. All users are advised to update to these erratum packages containing a backported patch which corrects these vulnerabilities. Red Hat would like to thank Michal Zalewski for finding and reporting this issue. 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.
