The largest vulnerability this week is a collection of bugs in the
OpenSSL library, affecting all applications that use OpenSSL SSL
functions (like Apache mod_ssl, stunnel, various IMAP and SMTP SSL/TLS
addons, etc.). These bugs are confirmed to be remotely exploitable.
It is reported in this issue as item {02.30.001}, in the Cross-Platform
category.
There's also a few Microsoft SQL Server patches which fix various
problems ({02.30.007} and {02.30.008}), as well as an Exchange 5.5
buffer overflow ({02.30.006}). Speaking of mail servers, Groupwise
6.0.1SP1 has a buffer overflow as well ({02.30.028}).
Finally, the DMCA has been dragged into yet another forum. A recent
CNET article sheds some disturbing light on how DMCA could be leveraged
against vulnerability research, as HP recently issued a rather harsh
warning to a research team: http://news.com.com/2100-1023-947325.html
Until next week,

*** {02.30.006} Win - MS02-037: Exchange SMTP EHLO response overflow
Microsoft released MS02-037 ("Exchange SMTP EHLO response overflow"). A
remote attacker can submit a particularly long EHLO parameter that,
when inserted into the EHLO response given by Exchange, will result in
a buffer overflow capable of executing arbitrary code with Exchange
service account privileges. Only Exchange version 5.5 is reported
vulnerable.
