- CVEs with nessus.description==According to the version of the vzkernel package and the readykernel-patch installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities :
- A flaw was found in how KVM handled exceptions delivered after Mov SS or Pop SS instructions have encountered a breakpoint. As a result, exceptions passed to the guest kernel could have wrong values on the stack. An unprivileged KVM guest user could use this flaw to crash the guest kernel or, potentially, escalate their privileges in the guest system.
- The implementation of ptrace in the kernel does not handle errors correctly when working with the debug registers. As a result, the hardware breakpoints could become corrupted. An unprivileged user could exploit this flaw to crash the kernel resulting in a denial-of-service, or, potentially, to escalate their privileges in the system.
Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
