Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated glibc packages fix vulnerabilities in resolver
Advisory ID: RHSA-2002:197-09
Issue date: 2002-09-10
Updated on: 2002-11-06
Product: Red Hat Linux
Keywords: glibc resolv DNS
Cross references:
Obsoletes: RHSA-2002:166-07
CVE Names: CAN-2002-1146
---------------------------------------------------------------------
1. Topic:
Updated glibc packages are available to fix a buffer overflow in the
resolver.
2. Relevant releases/architectures:
Red Hat Linux 6.2 - alpha, i386, sparc, sparcv9
Red Hat Linux 7.0 - alpha, alphaev6, i386, i686
Red Hat Linux 7.1 - alpha, alphaev6, i386, i686, ia64
Red Hat Linux 7.2 - i386, i686, ia64
Red Hat Linux 7.3 - i386, i686
3. Problem description:
The GNU C library package, glibc, contains standard libraries used by
multiple programs on the system.
A read buffer overflow vulnerability exists in the glibc resolver code in
versions of glibc up to and including 2.2.5. The vulnerability is
triggered by DNS packets larger than 1024 bytes and can cause applications
to crash.
All Red Hat Linux users are advised to upgrade to these errata packages
which contain a patch to correct this vulnerability.
This errata has been updated to work with programs querying DNS from
extremely small stack sizes, such as MySQL.
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):
75128 - MySQL hangs/crashes after glibc upgrade
73694 - forkexec and resulting stack limit differences (pthread vs. no pthread)
