The ELF

Fix 2 security bugs found in OpenSSH. A pre-authentication denial of service (found
by Tavis Ormandy) that would cause
sshd(8)
to spin until the login grace time expired.
An unsafe signal handler (found by Mark Dowd) that is vulnerable to a race condition
that could be exploited to perform a pre-authentication denial of service.

Several problems have been found in OpenSSL. While parsing certain invalid ASN.1
structures an error condition is mishandled, possibly resulting in an infinite
loop. A buffer overflow exists in the SSL_get_shared_ciphers function. A NULL
pointer may be dereferenced in the SSL version 2 client code. In addition, many
applications using OpenSSL do not perform any validation of the lengths of
public keys being used.

Two Denial of Service issues have been found with BIND.
An attacker who can perform recursive lookups on a DNS server and is able
to send a sufficiently large number of recursive queries, or is able to
get the DNS server to return more than one SIG(covered) RRsets can stop
the functionality of the DNS service.
An attacker querying an authoritative DNS server serving a RFC 2535
DNSSEC zone may be able to crash the DNS server.

A problem in
isakmpd(8)
caused IPsec to run partly without replay protection. If
isakmpd(8)
was acting as responder during SA negotiation, SA's with a replay window of size 0 were created.
An attacker could reinject sniffed IPsec packets, which will be accepted without checking the
replay counter.

httpd(8)'s
mod_rewrite has a potentially exploitable off-by-one buffer overflow.
The buffer overflow may result in a vulnerability which, in combination
with certain types of Rewrite rules in the web server configuration files,
could be triggered remotely. The default install is not affected by the
buffer overflow. CVE-2006-3747

A potential denial of service problem has been found in sendmail. A malformed MIME
message could trigger excessive recursion which will lead to stack exhaustion.
This denial of service attack only affects delivery of mail from the queue and
delivery of a malformed message. Other incoming mail is still accepted and
delivered. However, mail messages in the queue may not be reattempted if a
malformed MIME message exists.
