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 multiple vulnerabilities as referenced in the ALAS-2020-1469 advisory.

 - A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Out-Of-Bounds access in XkbSetNames function may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-14345)

 - A flaw was found in xorg-x11-server before 1.20.9. An integer underflow in the X input extension protocol decoding in the X server may lead to arbitrary access of memory contents. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-14346)

 - A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Integer underflow leading to heap- buffer overflow may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-14361, CVE-2020-14362)

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.
