Recently multiple servers of the Debian project were compromised
using a Debian developers account and an unknown root exploit.
Forensics revealed a burneye encrypted exploit. Robert van der
Meulen managed to decrypt the binary which revealed a kernel
exploit. Study of the exploit by the RedHat and SuSE kernel and
security teams quickly revealed that the exploit used an integer
overflow in the brk system call. Using this bug it is possible for
a userland program to trick the kernel into giving access to the
full kernel address space. This problem was found in September by
Andrew Morton, but unfortunately that was too late for the 2.4.22
kernel release.
This bug has been fixed in kernel version 2.4.23 for the 2.4
tree and 2.6.0-test6 kernel tree. For Debian it has been fixed in
version 2.4.18-12 of the kernel source packages, version 2.4.18-14
of the i386 kernel images and version 2.4.18-11 of the alpha kernel
images.
