Problem description

This security update fixes an integer overflow in the xdrmem_getbytes()- function that is part of the RPC (Remote Procedure Call) subsystem in the glibc. The resulting vulnerability may allow a remote attacker to execute arbitrary commands with the privileges of the user running the RPC application.
The flaw was discovered by researchers at eEye Digital Security. It is present in many implementations of the RPC protocol. The routine in question may be used by many applications using the RPC system for data exchange over the network.
Please note that the update for the glibc-devel patch does not have any immediate effect on running applications. The package glibc contains the shared libraries that are linked to a dynamically linked binary each time the binary is started. The glibc-devel package contains the static libraries for static linking. If you are using self-compiled statically linking binaries that make use of the RPC subsystem of the glibc, you should consider recompiling your applications.
Please also have a look at the corresponding glibc patch:
