Ubuntu 16.04 LTS : libseccomp-golang vulnerability (USN-4574-1)

high Nessus Plugin ID 141302

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-4574-1 advisory.

 It was discovered that libseccomp-golang did not properly generate BPFs. If a process were running under a restrictive seccomp filter that specified multiple syscall arguments, the application could potentially bypass the intended restrictions put in place by seccomp.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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 golang-github-seccomp-libseccomp-golang-dev package.
