Red Hat alert RHSA-2004:047-01 (PWLib)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated PWLib packages fix protocol security issues Advisory ID: RHSA-2004:047-01 Issue date: 2004-02-18 Updated on: 2004-02-18 Product: Red Hat Enterprise Linux Keywords: h323 h225 Cross references: Obsoletes: CVE Names: CAN-2004-0097 - --------------------------------------------------------------------- 1. Topic: Updated PWLib packages that contain fixes for security issues found during protocol testing by the NISCC are now available. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux ES version 3 - i386 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem description: PWLib is a cross-platform class library designed to support the OpenH323 project. OpenH323 provides an implementation of the ITU H.323 teleconferencing protocol, used by packages such as Gnome Meeting. A test suite for the H.225 protocol (part of the H.323 family) provided by the NISCC uncovered bugs in PWLib prior to version 1.6.0. An attacker could trigger these bugs by sending carefully crafted messages to an application. The effects of such an attack can vary depending on the application, but would usually result in a Denial of Service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0097 to this issue. Users are advised to upgrade to the erratum packages, which contain backported security fixes and are not vulnerable to these issues. Red Hat would like to thank Craig Southeren of the OpenH323 project for providing the fixes for 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. 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.
