Cross references:=20=20 Obsoletes: RHSA-2002:139 CVE Names: CAN-2002-0391 --------------------------------------------------------------------- 1. Topic: Updated glibc packages are available to fix a buffer overflow in the XDR decoder. 2. Relevant releases/architectures: Red Hat Linux 6.2 - alpha, i386, i686, 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 glibc package contains standard libraries which are used by multiple programs on the system. Sun RPC is a remote procedure call framework which allows clients to invoke procedures in a server process over a network. XDR is a mechanism for encoding data structures for use with RPC. NFS, NIS, and many other network services are built upon Sun RPC. glibc contains an XDR encoder/decoder derived from Sun's RPC implementation which was recently demonstrated to be vulnerable to a heap overflow. An error in the calculation of memory needed for unpacking arrays in the XDR decoder in glibc 2.2.5 and earlier can result in a heap buffer overflow. Depending upon the application, this vulnerability may be exploitable and lead to arbitrary code execution.=20=20 All users should upgrade to these errata packages which contain patches to the glibc libraries and therefore are not vulnerable to these issues. Thanks to Solar Designer for providing patches for this issue 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.0 5.
