Virtuozzo 6 : parallels-server-bm-release / vzkernel / etc (VZA-2017-096)

Medium Nessus Plugin ID 104130


The remote Virtuozzo host is missing a security update.


According to the version of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerability :

- A flaw was found in the implementation of associative arrays where the add_key systemcall and KEYCTL_UPDATE operations allowed for a NULL payload with a nonzero length. When accessing the payload within this length parameters value, an unprivileged user could trivially cause a NULL pointer dereference (kernel oops).

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 affected parallels-server-bm-release / vzkernel / etc package.
