Description

Xinetd receives a LTSS roll-up update to fix two security issues.

  • CVE-2012-0862: xinetd enabled all services when tcp multiplexing is used.

  • CVE-2013-4342: xinetd ignored user and group directives for tcpmux services, running services as root.

While both issues are not so problematic on their own, in combination the impact is greater and enabling tcpmux would be risky.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
