Tripwire is a system integrity assessment tool. Paul Herman discovered a format string vulnerability in Tripwire version 2.3.1 and earlier. If Tripwire is configured to send reports via email, a local user could gain privileges by creating a carefully crafted file. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0536 to this issue. Users of Tripwire are advised to upgrade to this erratum package which contains a backported security patch to correct this issue. The erratum package also contains some minor bug fixes. Updated packages: Red Hat Enterprise Linux AS (v. 2.1) -------------------------------------------------------------------------------- SRPMS: tripwire-2.3.1-18.src.rpm b5eae5cd1780f649cc9cd5d123d4bb5c i386: tripwire-2.3.1-18.i386.rpm ab6af85788d25ae312cbec3a768be2c8 Red Hat Enterprise Linux ES (v. 2.1) -------------------------------------------------------------------------------- SRPMS: tripwire-2.3.1-18.src.rpm b5eae5cd1780f649cc9cd5d123d4bb5c i386: tripwire-2.3.1-18.i386.rpm ab6af85788d25ae312cbec3a768be2c8 Red Hat Enterprise Linux WS (v. 2.1) -------------------------------------------------------------------------------- SRPMS: tripwire-2.3.1-18.src.rpm b5eae5cd1780f649cc9cd5d123d4bb5c i386: tripwire-2.3.1-18.i386.rpm ab6af85788d25ae312cbec3a768be2c8 (The unlinked packages above are only available from the Red Hat Network) 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 Bugs fixed: (see bugzilla for more information) 125176 - CAN-2004-0536 tripwire privilege escalation flaw 70502 - Old File Checks in sample policy configuration file 72259 - Missing policyguide.txt in tripwire RPM References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0536 http://marc.theaimsgroup.com/?l=bugtraq&m=108627481507249 -------------------------------------------------------------------------------- The listed packages are GPG signed by Red Hat, Inc. for security. Our key is available at: http://www.redhat.com/solutions/security/news/publickey/#key You can verify each package and see who signed it with the following command: rpm --checksig -v filename If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command: md5sum filename The Red Hat security contact is security@redhat.com.
