EulerOS Virtualization 3.0.2.0 : expat (EulerOS-SA-2023-1707)

critical Nessus Plugin ID 175190

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

 - xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks for whether a UTF-8 character is valid in a certain context. (CVE-2022-25235)

 - xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters into namespace URIs. (CVE-2022-25236)

 - libexpat before 2.4.9 has a use-after-free in the doContent function in xmlparse.c. (CVE-2022-40674)

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 expat packages.
