Package: openssl Version: 0.9.8-2 Severity: important Tags: security Yutaka Oiwa found a vulnerability in OpenSSL:
A vulnerability has been found in all previously released versions of OpenSSL (all versions up to 0.9.7h and 0.9.8a). Versions 0.9.7h and 0.9.8a have been released to address the issue. The vulnerability potentially affects applications that use the SSL/TLS server implementation provided by OpenSSL. Such applications are affected if they use the option SSL_OP_MSIE_SSLV2_RSA_PADDING. This option is implied by use of SSL_OP_ALL, which is intended to work around various bugs in third-party software that might prevent interoperability. The SSL_OP_MSIE_SSLV2_RSA_PADDING option disables 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" can force a client and a server to negotiate the SSL 2.0 protocol even if these parties both support 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. Applications using neither SSL_OP_MSIE_SSLV2_RSA_PADDING nor SSL_OP_ALL are not affected. Also, applications that disable use of SSL 2.0 are not affected. Please see http://www.openssl.org/news/secadv_20051011.txt for the full advisory, which contains patches for 0.9.7 and 0.9.8. This has been assigned CAN-2005-2969, please mention so in the changelog when fixing this.
