Debian 3.0 DSA 427-1 Critical: mremap Local Attack Exploit

Paul Starzetz discovered a flaw in bounds checking in mremap() in the
Linux kernel (present in version 2.4.x and 2.6.x) which may allow a
local attacker to gain root privileges. Version 2.2 is not affected
by this bug.

For the stable distribution (woody) this problem has been fixed in
version 2.4.17-0.020226.2.woody3 the mips and mipsel architectures.

For the unstable distribution (sid) this problem will be fixed soon
with newly uploaded packages.

We recommend that you upgrade your kernel packages. This problem has
been fixed in the upstream version 2.4.24 as well.
