Red Hat Security Advisory Synopsis: Updated icecast packages are available Advisory ID: RHSA-2002:063-05 Issue date: 2002-04-11 Updated on: 2002-04-24 Product: Red Hat Powertools Keywords: icecast buffer overflow DoS long get request Cross references: Obsoletes: RHSA-2001:004 - --------------------------------------------------------------------- 1. Topic: Updated icecast packages are available which fix a number of security issues. 2. Relevant releases/architectures: Red Hat Powertools 7.0 - alpha, i386 Red Hat Powertools 7.1 - alpha, i386 3. Problem description: Icecast is a mp3-based broadcasting system. Buffer overflows in Icecast 1.3.11 and earlier allow remote attackers to execute arbitrary code via a long HTTP GET request. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-0177 to this issue. Additional buffer overflow vulnerabilities exist in previous versions of Icecast that are also fixed by this update. These vulnerabilities can cause denial of service attacks as well as arbitrary code execution. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2001-0784, CAN-2001-1083, CAN-2001-1229, and CAN-2001-1230 to these issues. Users of Icecast are advised to update to the errata packages containing Icecast 1.3.12 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.
