high Nessus Plugin ID 182980

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the bd92f1ab-690c-11ee-9ed0-001fc69cd6dc advisory.

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

Solution

Update the affected packages.
