USN-204-1: SSL library vulnerability
Posted on: 10/14/2005 02:12 AM

A new SSL library vulnerability update is available for Ubuntu Linux. Here the announcement:

Ubuntu Security Notice USN-204-1 October 14, 2005
openssl vulnerability

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)

The following packages are affected:


The problem can be corrected by upgrading the affected package to
version 0.9.7d-3ubuntu0.3 (for Ubuntu 4.10), 0.9.7e-3ubuntu0.2 (for
Ubuntu 5.04), or 0.9.7g-1ubuntu1.1 (for Ubuntu 5.10). Since the SSL
library is used by a lot of server and desktop applications, you
should restart your computer after a standard system upgrade to ensure
that all programs use the new library.

Details follow:

Yutaka Oiwa discovered a possible cryptographic weakness in OpenSSL
applications. Applications using the OpenSSL library can use the
SSL_OP_MSIE_SSLV2_RSA_PADDING option (or SSL_OP_ALL, which implies the
former) to maintain compatibility with third party products, which is
achieved by working around known bugs in them.

The SSL_OP_MSIE_SSLV2_RSA_PADDING option disabled a verification step
in the SSL 2.0 server supposed to prevent active protocol-version
rollback attacks. With this verification step disabled, an attacker
acting as a "man in the middle" could force a client and a server to
negotiate the SSL 2.0 protocol even if these parties both supported
SSL 3.0 or TLS 1.0. The SSL 2.0 protocol is known to have severe
cryptographic weaknesses and is supported as a fallback only.
