Mandrake Linux Security Update Advisory

---

---

Problem Description:

A vulnerability was discovered in the Linux kernel versions
2.4.22 and previous. A flaw in bounds checking in the do_brk()
function can allow a local attacker to gain root privileges. This
vulnerability is known to be exploitable; an exploit is in the wild
at this time.

The Mandrake Linux 9.2 kernels are not vulnerable to this
problem as the fix for it is already present in those kernels.

MandrakeSoft encourages all users to upgrade their systems
immediately.
