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. - "The evil that men do lives after them; the good that men do is often interred with their bones." --Shakespeare, Julius Caesar. ----------------------------------------------------------------------- Public PGP key at: http://pgp.mit.edu pub 1024D/98D3363F 2003/08/16 Plamen Tonev (MiCRoPhoBIC) <[EMAIL PROTECTED]> Key fingerprint = 5D08 C610 0F09 618E 3515 5C87 0F62 3808 98D3 363F ------------------------------------------------------------------------
