Opera, possibly before 9.25, processes a 3xx HTTP CONNECT response before a successful SSL handshake, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying this CONNECT response to specify a 302 redirect to an arbitrary https web site.

The remote host is affected by the vulnerability described in GLSA-201206-03 (Opera: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Opera. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted web       page, possibly resulting in execution of arbitrary code with the       privileges of the process or a Denial of Service condition. A remote       attacker may be able to: trick users into downloading and executing       arbitrary files, bypass intended access restrictions, spoof trusted       content, spoof URLs, bypass the Same Origin Policy, obtain sensitive       information, force subscriptions to arbitrary feeds, bypass the popup       blocker, bypass CSS filtering, conduct cross-site scripting attacks, or       have other unknown impact.
    A local attacker could perform symlink attacks to overwrite arbitrary       files with the privileges of the user running the application or possibly       obtain sensitive information.
    A physically proximate attacker may be able to access an email account.
  Workaround :

    There is no known workaround at this time.

Opera version 10 includes at least security fixes for an XML denial-of-service bug (CVE-2009-1234) and the 'SSL tampering' attack (CVE-2009-2059, CVE-2009-2063, CVE-2009-2067, CVE-2009-2070).

The version of Safari installed on the remote Windows host is earlier than 3.2.2.  Such versions reportedly have multiple vulnerabilities : 

  - Multiple input validation issues in their handling of 'feed: ' URLs, which could be abused to execute arbitrary JavaScript code in the local security zone. (CVE-2009-0137)

  - A cached certificate is not required before displaying a lock icon for a HTTPS web site. This allows a man-in-the-middle attacker to present the user with spoofed web pages over HTTPS that appear to be from a legitimate source. (CVE-2009-2072)

  - The browser processes a 3xxx HTTP CONNECT before a successful SSL handshake, which could allow a man-in-the-midddle attacker to execute arbitrary script code in the context of a HTTPS site. (CVE-2009-2062)

 The version of Opera installed on the remote host reportedly is affected by several issues : 

 - An issue where TLS certificates could be used to execute arbitrary code.

 - The browser processes a 3xx HTTP CONNECT response before a successful SSL handshake, which could allow a man-in-the-middle attacker to execute arbitrary web script in the context of a HTTPS server.

The version of Opera installed on the remote host reportedly is affected by several issues, including one in which TLS certificates could be used to execute arbitrary code.
