Further analysis of the upstream patch and DLA-3495-1 version helped to identify that the vulnerability was still present due to DLA 3495-1 not including commit 7adf00f9, which added chroot checks to one of the code path. Special thanks to Camila Camargo de Matos of Ubuntu security team. For Debian 10 buster, this problem has been fixed in version 0.6.2+dfsg-3+deb10u2. We recommend that you upgrade your php-dompdf packages.

Red Hat 9 RHSA-2004:154-01 Critical: CVS Client Exploitation

Updated cvs packages that fix a client vulnerability that could be exploited by a malicious server are now available.. Red Hat Security Advisory Synopsis: Updated CVS packages fix security issue Advisory ID: RHSA-2004:154-01 Issue date: 2004-04-14 Updated on: 2004-04-14 Product: Red Hat Linux Keywords: Cross references: Obsoletes: RHSA-2004:003 CVE Names: CAN-2004-0180 - --------------------------------------------------------------------- 1. Topic: Updated cvs packages that fix a client vulnerability that could be exploited by a malicious server are now available. 2. Relevant releases/architectures: Red Hat Linux 9 - i386 3. Problem description: CVS is a version control system frequently used to manage source code repositories. Sebastian Krahmer discovered a flaw in CVS clients where rcs diff files can create files with absolute pathnames. An attacker could create a fake malicious CVS server that would cause arbitrary files to be created or overwritten when a victim connects to it. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0180 to this issue. Users of CVS are advised to upgrade to these erratum packages, which contain a patch correcting 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 followingcommand: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. RPMs required: Red Hat Linux 9: SRPMS: i386: 6.
