EulerOS 2.0 SP9 : libxml2 (EulerOS-SA-2023-3343)

medium Nessus Plugin ID 188349

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails.
 This occurs in xmlUnlinkNode in tree.c. NOTE: the vendor's position is 'I don't think these issues are critical enough to warrant a CVE ID ... because an attacker typically can't control when memory allocations fail.' (CVE-2023-45322)

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.
