EulerOS 2.0 SP8 : libxml2 (EulerOS-SA-2024-2040)

high Nessus Plugin ID 202947

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

An issue was discovered in libxml2 before 2.11.7 and 2.12.x before 2.12.5. When using the XML Reader interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to an xmlValidatePopElement use-after-free.(CVE-2024-25062)

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)

Tenable has extracted the preceding description block directly from the EulerOS libxml2 security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libxml2 packages.
