Various versions of the ISC BIND resolver libraries are vulnerable to a

buffer overflow attack. Updated BIND packages are now available to fix

this issue.



ISC BIND (Berkeley Internet Name Domain) is an implementation of the DNS

(Domain Name System) protocols. BIND includes a DNS server (named),

which resolves host names to IP addresses; a resolver library

(routines for applications to use when interfacing with DNS); and

various tools.



A buffer overflow vulnerability exists in multiple implementations of DNS

resolver libraries. Applications that utilize vulnerable DNS resolver

libraries may be affected. A remote attacker who is able to send malicious

DNS responses could potentially exploit this vulnerability to execute

arbitrary code or cause a denial of service on a vulnerable system.



Red Hat Linux does not ship with any applications or libraries that link

against the BIND resolver libraries; however, third party code may be affected.



The updated bind packages included in this errata contain the patches from

8.3.3 which fix the buffer overflow applied (backported) to the 9.2.1 sources.

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.
