Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the libX11 package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- A vulnerability was found in libX11 due to a boundary condition within the _XkbReadKeySyms() function.
This flaw allows a local user to trigger an out-of-bounds read error and read the contents of memory on the system. (CVE-2023-43785)

- A vulnerability was found in libX11 due to an infinite loop within the PutSubImage() function. This flaw allows a local user to consume all available system resources and cause a denial of service condition.
(CVE-2023-43786)

- A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function. This flaw allows a local user to trigger an integer overflow and execute arbitrary code with elevated privileges. (CVE-2023-43787)

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.
