                   Red Hat Security Advisory 
 
Synopsis:          Updated xinetd packages fix a denial-of-service attack and other bugs 
Advisory ID:       RHSA-2003:160-01 
Issue date:        2003-05-13 
Updated on:        2003-05-13 
Product:           Red Hat Linux 
Keywords:           
Cross references:   
Obsoletes:          
CVE Names:         CAN-2003-0211 
--------------------------------------------------------------------- 
 
1. Topic: 
 
Updated xinetd packages that fix a security vulnerability are now avaliable. 
 
2. Relevant releases/architectures: 
 
Red Hat Linux 7.1 - i386 
Red Hat Linux 7.2 - i386, ia64 
Red Hat Linux 7.3 - i386 
Red Hat Linux 8.0 - i386 
Red Hat Linux 9 - i386 
 
3. Problem description: 
 
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. 
 
4. Solution: 
 
Before applying this update, make sure all previously released errata 
relevant to your system have been applied. 
 
To update all RPMs for your particular architecture, run: 
 
rpm -Fvh [filenames] 
 
where [filenames] is a list of the RPMs you wish to upgrade.  Only those 
RPMs which are currently installed will be updated.  Those RPMs which are 
not installed but included in the list will not be updated.  Note that you 
can also use wildcards (*.rpm) if your current directory *only* contains the 
desired RPMs. 
 
Please note that this update is also available via Red Hat Network.  Many 
people find this an easier way to apply updates.  To use Red Hat Network, 
launch the Red Hat Update Agent with the following command: 
 
up2date 
 
This will start an interactive process that will result in the appropriate 
RPMs being upgraded on your system. 
 
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 
 
86304 - loadavg ability(max_load attribute) is not supported 
86297 - Server arg "-reuse" is meaningless in /etc/init.d/xinetd 
85530 - Typo in /etc/init.d/xinetd 
78699 - xinetd reload kills all services if exactly nine services are enabled 
88537 - CAN-2003-0211 xinetd leaks memory 
87863 - socket leak 
85371 - xinetd  regression - doesn't accept valid facility on log_type SYSLOG (e.g. mail) 
84840 - tcpmux based services cannot be used 
79274 - Xinetd v 2.3.7-4.7x redirects fail to start 
79085 - not updated via up2date 
78903 - xinetd redirect does not work after update 
77781 - xinetd stop serving the services because "Too many open files"
