Synopsis

The remote Red Hat host is missing a security update.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2019:3624 advisory.

The libseccomp library provides an interface to the Linux Kernel's syscall filtering mechanism, seccomp.
The libseccomp API allows an application to specify which system calls or system call arguments the application is allowed to execute, all of which are then enforced by the Linux Kernel.

The following packages have been upgraded to a later upstream version: libseccomp (2.4.1). (BZ#1688938)

Security Fix(es):

* libseccomp: incorrect generation of syscall filters in libseccomp (CVE-2019-9893)

Additional Changes:

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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 libseccomp and / or libseccomp-devel packages.
