Virtuozzo 7 : readykernel-patch (VZA-2017-120)

High Nessus Plugin ID 105464


The remote Virtuozzo host is missing a security update.


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 vulnerability :

- The sctp_do_peeloff() function in the Linux kernel before 4.14 did not check whether the intended netns was used in a peel-off action, which allowed local users to cause a denial of service (use-after-free in sctp_cmp_addr_exact() resulting in system crash) or possibly have unspecified other impact via crafted system calls.

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.


Update the readykernel patch.
