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.
