eEye Digital Security discovered an integer overflow in the xdrmem_getbytes() function which is also present in GNU libc. This function is part of the XDR (external data representation) encoder/decoder derived from Sun's RPC implementation. Depending upon the application, this vulnerability can cause buffer overflows and could possibly be exploited to execute arbitray code.
For the stable distribution (woody) this problem has been fixed in version 2.2.5-11.5.
For the old stable distribution (potato) this problem has been fixed in version 2.1.3-25.
For the unstable distribution (sid) this problem has been fixed in version 2.3.1-16.
