According to the versions of the libX11 packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following 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)

  - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:1804 advisory.

  - 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.
