Rocky Linux 8 : container-tools:rhel8 (RLSA-2019:0975)

high Nessus Plugin ID 185070

Synopsis

The remote Rocky Linux host is missing a security update.

Description

The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2019:0975 advisory.

 - runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.
 (CVE-2019-5736)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
