Title:	Debian: Security Advisory (DLA-3172-1)
Summary:	The remote host is missing an update for the Debian 'libxml2' package(s) announced via the DLA-3172-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'libxml2' package(s) announced via the DLA-3172-1 advisory. Vulnerability Insight: It was discovered that libxml2, the GNOME XML library, was vulnerable to integer overflows and memory corruption. CVE-2022-40303 Parsing a XML document with the XML_PARSE_HUGE option enabled can result in an integer overflow because safety checks were missing in some functions. Also, the xmlParseEntityValue function did not have any length limitation. CVE-2022-40304 When a reference cycle is detected in the XML entity cleanup function the XML entity data can be stored in a dictionary. In this case, the dictionary becomes corrupted resulting in logic errors, including memory errors like double free. For Debian 10 buster, these problems have been fixed in version 2.9.4+dfsg1-7+deb10u5. We recommend that you upgrade your libxml2 packages. For the detailed security status of libxml2 please refer to its security tracker page at: [link moved to references] Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references] Affected Software/OS: 'libxml2' package(s) on Debian 10. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
