EulerOS Virtualization 2.10.1 : libxml2 (EulerOS-SA-2022-2113)

medium Nessus Plugin ID 163213

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the versions of the libxml2 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) don't check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2's buffer functions, for example libxslt through 1.1.35, is affected as well. (CVE-2022-29824)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libxml2 packages.
