**Name of the Vulnerable Software and Affected Versions** libxml2 versions prior to 2.11.8 libxml2 versions 2.12.x prior to 2.12.7 **Description** An issue was discovered in xmllint, which is part of libxml2. The problem arises when formatting error messages with xmllint --htmlout, resulting in a buffer over-read in xmlHTMLPrintFileContext in xmllint.c. This can potentially lead to a denial of service. **Recommendations** For libxml2 versions prior to 2.11.8, update to version 2.11.8 or later. For libxml2 versions 2.12.x prior to 2.12.7, update to version 2.12.7 or later. As a temporary workaround, consider avoiding the use of xmllint --htmlout until a patch is applied.

**Name of the Vulnerable Software and Affected Versions** OpenStack Cinder versions 7.0.0 through 7.0.1 and 8.0.0 through 8.1.1 and prior to 9.0.0 OpenStack Glance versions prior to 11.0.1 and 12.0.0 and prior to 14.0.0 OpenStack Nova versions prior to 12.0.4 and 13.0.0 **Description** The image parser in OpenStack does not properly limit `qemu-img` calls, which might allow attackers to cause a denial of service via a crafted disk image, leading to memory and disk consumption. **Recommendations** For OpenStack Cinder versions 7.0.0 through 7.0.1, update to version 7.0.2 or 9.0.0. For OpenStack Cinder versions 8.0.0 through 8.1.1, update to version 9.0.0. For OpenStack Glance versions prior to 11.0.1, update to version 11.0.1 or 14.0.0. For OpenStack Glance versions 12.0.0 but prior to 14.0.0, update to version 14.0.0. For OpenStack Nova versions prior to 12.0.4, update to version 12.0.4. For OpenStack Nova versions 13.0.0, no specific fix is mentioned, consider updating to a newer version if available.
