Amazon Linux AMI : libX11 (ALAS-2020-1463) (deprecated)

high Nessus Plugin ID 144461

Language:

Synopsis

This plugin has been deprecated.

Description

The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1463 advisory.

 - An integer overflow vulnerability leading to a double-free was found in libX11. This flaw allows a local privileged attacker to cause an application compiled with libX11 to crash, or in some cases, result in arbitrary code execution. The highest threat from this flaw is to confidentiality, integrity as well as system availability. (CVE-2020-14363)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

This plugin has been deprecated due to Amazon pulling the previously published advisory.
