Ubuntu 10.04 LTS / 10.10 / 11.04 : mutt vulnerability (USN-1221-1)

It was discovered that mutt incorrectly verified the hostname in an SSL certificate. An attacker could trick mutt into trusting a rogue SMTPS, IMAPS, or POP3S server's certificate, which was signed by a trusted certificate authority, to perform a man-in-the-middle attack. Note that Tenable Networ...

ssl/t1lib.c in OpenSSL 0.9.8h through 0.9.8q and 1.0.0 through 1.0.0c allows remote attackers to cause a denial of service crash, and possibly obtain sensitive information in applications that use OpenSSL, via a malformed ClientHello handshake message that triggers an out-of-bounds memory access,...

OpenSSL SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG Session Resume Ciphersuite Downgrade Issue

The version of OpenSSL on the remote host has been shown to allow resuming session with a weaker cipher than was used when the session was initiated. This means that an attacker that sees i.e., by sniffing the start of an SSL connection can manipulate the OpenSSL session cache to cause subsequent...

Security Writer Questions Impact of SSL Flaw

Let’s try to separate the wheat from the chaff. Let’s start by looking at the vulnerability itself. It is a “man-in-the-middle” MitM attack in which an attacker can use an SSL feature called “negotiation” to inject bad stuff into an SSL session. Right, so that’s not good news. But the sky isn’t...
