Summary
Red Hat Security Advisory: : Updated xinetd packages fix a denial-of-service attack and other bugs
Notes
Topic
Updated xinetd packages that fix a security vulnerability are now avaliable.
Details
Xinetd is a 'master server' that is used to to accept service connection
requests and start the appropriate servers.
Because of a programming error, memory was allocated and never freed if a
connection was refused for any reason. An attacker could exploit this flaw
to crash the xinetd server, rendering all services it controls unavaliable.
In addition, other flaws in xinetd could cause incorrect operation in
certain unusual server configurations.
All users of xinetd are advised to update to the packages listed in this
erratum, which contain an upgrade to xinetd-2.3.11 and are not vulnerable
to these issues.

"details": "Before applying this update, make sure all previously released errata\nrelevant to your system have been applied.\n\nTo update all RPMs for your particular architecture, run:\n\nrpm -Fvh [filenames]\n\nwhere [filenames] is a list of the RPMs you wish to upgrade. Only those\nRPMs which are currently installed will be updated. Those RPMs which are\nnot installed but included in the list will not be updated. Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network. Many\npeople find this an easier way to apply updates. To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.",
