The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4483-1 advisory.

  - A vulnerability was found in X.Org. This security flaw occurs because the XkbCopyNames function left a     dangling pointer to freed memory, resulting in out-of-bounds memory access on subsequent XkbGetKbdByName     requests.. This issue can lead to local privileges elevation on systems where the X server is running     privileged and remote code execution for ssh X forwarding sessions. (CVE-2022-4283)

  - A vulnerability was found in X.Org. This security flaw occurs becuase the swap handler for the     XTestFakeInput request of the XTest extension may corrupt the stack if GenericEvents with lengths larger     than 32 bytes are sent through a the XTestFakeInput request. This issue can lead to local privileges     elevation on systems where the X server is running privileged and remote code execution for ssh X     forwarding sessions. This issue does not affect systems where client and server use the same byte order.
    (CVE-2022-46340)

  - A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIPassiveUngrab     request accesses out-of-bounds memory when invoked with a high keycode or button code.

According to the versions of the xorg-x11-server packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the Xorg-x11-server. An out-of-bounds access issue can occur in the ProcXkbSetGeometry     function due to improper validation of the request length. (CVE-2022-2319)

  - A flaw was found in the Xorg-x11-server. The specific flaw exists within the handling of     ProcXkbSetDeviceInfo requests. The issue results from the lack of proper validation of user-supplied data,     which can result in a memory access past the end of an allocated buffer. This flaw allows an attacker to     escalate privileges and execute arbitrary code in the context of root. (CVE-2022-2320)

  - A vulnerability classified as critical was found in X.org Server. Affected by this vulnerability is the     function _GetCountedString of the file xkb/xkb.c. The manipulation leads to buffer overflow. It is     recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is     VDB-211051. (CVE-2022-3550)

  - A vulnerability, which was classified as problematic, has been found in X.org Server. Affected by this     issue is the function ProcXkbGetKbdByName of the file xkb/xkb.c. The manipulation leads to memory leak. It     is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211052.
