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.

 - libseccomp-golang 0.9.0 and earlier incorrectly generates BPFs that OR multiple arguments rather than ANDing them. A process running under a restrictive seccomp filter that specified multiple syscall arguments could bypass intended access restrictions by specifying a single matching argument.
 (CVE-2017-18367)

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.
