#1 OpenSSL Server Name extension crash Testing using the Codenomicon TLS test suite discovered a flaw in the handling of server name extension data in OpenSSL 0.9.8f and OpenSSL 0.9.8g. If OpenSSL has been compiled using the non-default TLS server name extensions, a remote attacker could send a carefully crafted packet to a server application using OpenSSL and cause a crash. (CVE-2008-0891). Please note this issue does not affect any other released versions of OpenSSL, and does not affect versions compiled without TLS server name extensions. ... #2 OpenSSL Omit Server Key Exchange message crash Testing using the Codenomicon TLS test suite discovered a flaw if the 'Server Key exchange message' is omitted from a TLS handshake in OpenSSL 0.9.8f and OpenSSL 0.9.8g. If a client connects to a malicious server with particular cipher suites, the server could cause the client to crash. (CVE-2008-1672). vapier, do we support these "non-default TLS server name extensions"? I'll attach upstream patches, please prepare ebuilds and we can do prestable testing on this bug. Do not commit anything to CVS yet. Created attachment 154341 [details, diff]

Since the embargo is off in ~36 hours, let me know if you intend to do prestable testing (preferred by security), or want to bump to the release directly in the tree. In case of the former, attach ebuild incorporating the patches to this bug. This is now public via http://www.openssl.org/news/secadv_20080528.txt 0.9.8h has been released to adress the issue, please bump the ebuild. Well to further complicate this, I'm having several SSL services that are no longer accessible from a client using openssl 0.9.8h while they're accessible from all versions below 0.9.8h. I don't know if this relates to tlsext but infra will be interested since one of my affected services is LDAP. Doug, do you experience the same issues using 0.9.8g + the patches on the bug? even though we have 0.9.8h, it's way too new to consider for stable ... we should apply the patches to 0.9.8g if Doug could get back to us quickly, that'd be good ... yeah yeah. Gimme a minute. I had a busy day today. Alright. We look golden. My issue is obviously something in 0.9.8h not related to the security fixes. I'll just make a new bug on that to figure it out. Who knows, maybe upstream is already aware. Anyway, I had to strip out the diff for CHANGES to get the patches to apply. But I added them to openssl-0.9.8g-r2 to the tree. Thanks for bumping!
