RHSA-2019:3624 - Security Advisory

  • Overview
  • Updated Packages

Synopsis

Moderate: libseccomp security, bug fix, and enhancement update

Type/Severity

Security Advisory: Moderate

Topic

An update for libseccomp is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

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)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Additional Changes:

For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.1 Release Notes linked from the References section.
