Description

According to the version of the mesa packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  • An exploitable shared memory permissions vulnerability exists in the functionality of X11 Mesa 3D Graphics Library 19.1.2. An attacker can access the shared memory without any specific permissions to trigger this vulnerability.(CVE-2019-5068)

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.
