<strong>004: SECURITY FIX: November 26, 2009</strong>

<i>All architectures</i><br>

The SSL/TLS protocol is subject to man-in-the-middle attacks related to
|
|
renegotiation (see CVE-2009-3555, draft-ietf-tls-renegotiation-00).
|
|
OpenSSL permitted this protocol feature by default and had no way to

disable it.

By using ptrace(2) on an ancestor process, a loop in the process tree
|
|
could be created, violating assumptions in other parts of the kernel
|

<strong>006: SECURITY FIX: March 12, 2010</strong>

OpenSSL is susceptible to a buffer overflow due to a failure

|
to check for NULL returns from bn_wexpand function calls.

Due to a null pointer dereference, it would be possible to crash ftpd when

handling glob(3)'ing requests. This is non-exploitable.

When decrypting packets, the internal decryption functions were not
|
|
paranoid enough in checking for underruns, which could potentially
|
|
lead to crashes.

When updating sensors showing the state of RAID volumes

<a href="https://man.openbsd.org/OpenBSD-4.6/mpi.4">mpi(4)</a>

|
allocates temporary memory and then returns it to the kernel as

device memory.

This causes kernel memory usage to be misrepresented, eventually

leading to a denial of service when a resource limit is apparently
|
|
reached.
