Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the versions of the openjpeg2 package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- There's a flaw in openjpeg's t2 encoder in versions prior to 2.4.0. An attacker who is able to provide crafted input to be processed by openjpeg could cause a null pointer dereference. The highest impact of this flaw is to application availability. (CVE-2020-27842)

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 openjpeg2 packages.
