Description

From Red Hat Security Advisory 2018:2308 :

An update for openslp is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Important. 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.

OpenSLP is an open source implementation of the Service Location Protocol (SLP) which is an Internet Engineering Task Force (IETF) standards track protocol and provides a framework to allow networking applications to discover the existence, location, and configuration of networked services in enterprise networks.

Security Fix(es) :

  • openslp: Heap memory corruption in slpd/slpd_process.c allows denial of service or potentially code execution (CVE-2017-17833)

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