Debian Security Advisory DSA 272-1 [email protected] Martin Schulze
March 28th, 2003
- --------------------------------------------------------------------------

Package : dietlibc
Vulnerability : integer overflow
Problem-Type : remote
Debian-specific: no
CVE Id : CAN-2003-0028
CERT advisory : VU#516825 CA-2003-10

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

For the unstable distribution (sid) this problem has been
fixed in version 0.22-2.

We recommend that you upgrade your dietlibc packages.
