Debian: dietlibc buffer overflow vulnerability
Summary
eEye Digital Security discovered an integer overflow in the
xdrmem_getbytes() function of glibc, that is also present in dietlibc,
a small libc useful especially for small and embedded systems. This
function is part of the XDR 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 0.12-2.5.
The old stable distribution (potato) does not contain dietlibc
packages.
For the unstable distribution (sid) this problem has been
fixed in version 0.22-2.
We recommend that you upgrade your dietlibc packages.
