NewStart CGSL MAIN 6.02 : xorg-x11-server Multiple Vulnerabilities (NS-SA-2022-0049)
high Nessus Plugin ID 160787
Synopsis
The remote NewStart CGSL host is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version MAIN 6.02, has xorg-x11-server packages installed that are affected by multiple vulnerabilities:- An integer overflow leading to a heap-buffer overflow was found in The X Input Method (XIM) client was implemented in libX11 before version 1.6.10. As per upstream this is security relevant when setuid programs call XIM client functions while running with elevated privileges. No such programs are shipped with Red Hat Enterprise Linux. (CVE-2020-14344)
- 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)
- 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)
- 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 these issues but has instead relied only on the application's self-reported version number.
