The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-0045 advisory.

  - A vulnerability was found in X.Org. This security flaw occurs because the handler for the     ScreenSaverSetAttributes request may write to memory after it has been freed. 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-2022-46343)

  - 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.
