GENTOO LINUX SECURITY ANNOUNCEMENT

PACKAGE :glibc
SUMMARY :division by zero

Wolfram Gloger discovered that the sunrpc overflow bugfix unintentially replaced potential integer overflows in connection with malloc() with more likely divisions by zero.
DETAIL
The XDR (external data representation) libraries are used to provide platform-independent methods for sending data from one system process to another, typically over a network connection. Such routines are commonly used in remote procedure call (RPC) implementations to provide transparency to application programmers who need to use common interfaces to interact with many different types of systems. The xdr_array() function in the XDR library provided by Sun Microsystems contains an integer overflow that can lead to improperly sized dynamic memory allocation. Subsequent problems like buffer overflows may result, depending on how and where the vulnerable xdr_array() function is used.

SOLUTION
It is recommended that all Gentoo Linux users who are running sys-libs/glibc-2.2.5-r6 and earlier update their systems as follows:
emerge rsync
emerge glibc
emerge clean
