       SCO Security Advisory

Subject:    UnixWare 7.1.3 UnixWare 7.1.4 : OpenSSL Potential SSL 2.0 Rollback Vulnerability
Advisory number:  SCOSA-2005.48
Issue date:    2005 November 15
Cross reference:  fz533160
       CVE-2005-2969
______________________________________________________________________________


1. Problem Description

   A vulnerability has been found in OpenSSL which 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.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)
   has assigned the name CVE-2005-2969 to this issue.
