Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has xorg-x11-server packages installed that are affected by multiple vulnerabilities:

- 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 the way xserver memory was not properly initialized. This could leak parts of server memory to the X client. In cases where Xorg server runs with elevated privileges, this could result in possible ASLR bypass. Xorg-server before version 1.20.9 is vulnerable. (CVE-2020-14347)

- A flaw was found in the X.Org Server before version 1.20.10. An out-of-bounds access in the XkbSetMap 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-2020-14360)

- 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)

- A flaw was found in xorg-x11-server before 1.20.10. A heap-buffer overflow in XkbSetDeviceInfo 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-2020-25712)

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