Virtuozzo 7 : readykernel-patch (VZA-2020-038)

Medium Nessus Plugin ID 136805

Synopsis

The remote Virtuozzo host is missing a security update.

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 vulnerability :

- [3.10.0-862.20.2.vz7.73.24 to 3.10.0-1062.4.2.vz7.116.7] Use-after-free read in napi_gro_frags(). A flaw was found in the implementation of GRO, which allows an attacker with local access to trigger a use-after-free read in napi_gro_frags() and, potentially, crash 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.

Solution

Update the readykernel patch.
