"I'm sure we all seen this already, but some crypto researchers found a timing vulnerability in OpenSSL. Only seems to affect release prior to 0.9.6i and 0.9.7a.

A patch is available for your OpenSSL source tree. Anyone know if recent releases of OpenBSD require patching? A cursory look at /usr/src/lib/libssl/src/CHANGES indicate it's a patched 0.9.6b release."

Actually, it was just updated this evening. According to errata.html , a patch for 3.2 has been released. Patch 007 fixes two issues in OpenSSL. It does not appear to be ported to the 3.1 release. This is the CVE entry CAN-2003-0078 , for those keeping track.
UPDATE: Patch 021 for 3.1-stable fixes this problem. Thanks, clvrmnky.

    yes you do need to patch 3.2 with this. if you follow -STABLE you just need to go into /usr/src/lib/libssl and rebuild. you might also notice that some net code was changed in src/sys so you can rebuild your kernel also (not sure what the changes are right now).

    The CVS tree reflects the changes for the 007_ssl patch and a pre-built binary patch is already available for i386.

    Thanks to all of you tracking binpatch, for your comments and support.

    What type of threat does this vulnerability impose?

    There's a patch for 3.1 , as well.
