Mozilla Firefox before 3.0.10 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-201301-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox,       Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information,       bypass restrictions and protection mechanisms, force file downloads,       conduct XML injection attacks, conduct XSS attacks, bypass the Same       Origin Policy, spoof URL&rsquo;s for phishing attacks, trigger a vertical       scroll, spoof the location bar, spoof an SSL indicator, modify the       browser&rsquo;s font, conduct clickjacking attacks, or have other unspecified       impact.
    A local attacker could gain escalated privileges, obtain sensitive       information, or replace an arbitrary downloaded file.
  Workaround :

    There is no known workaround at this time.

Security vulnerabilities have been discovered and corrected in Mozilla Firefox 3.x :

CVE-2009-1392: Firefox browser engine crashes CVE-2009-1832: Firefox double frame construction flaw CVE-2009-1833: Firefox JavaScript engine crashes CVE-2009-1834: Firefox URL spoofing with invalid unicode characters CVE-2009-1835: Firefox Arbitrary domain cookie access by local file: resources CVE-2009-1836: Firefox SSL tampering via non-200 responses to proxy CONNECT requests CVE-2009-1837: Firefox Race condition while accessing the private data of a NPObject JS wrapper class object CVE-2009-1838: Firefox arbitrary code execution flaw CVE-2009-1839: Firefox information disclosure flaw CVE-2009-1840:
Firefox XUL scripts skip some security checks CVE-2009-1841: Firefox JavaScript arbitrary code execution CVE-2009-2043: firefox - remote TinyMCE denial of service CVE-2009-2044: firefox - remote GIF denial of service CVE-2009-2061: firefox - man-in-the-middle exploit CVE-2009-2065: firefox - man-in-the-middle exploit

This update provides the latest Mozilla Firefox 3.x to correct these issues.

Additionally, some packages which require so, have been rebuilt and are being provided as updates.

The version of Firefox installed on the remote host is earlier than 3.0.10.  Such versions have multiple vulnerabilities :

  - An error in function '@nsTextFrame::ClearTextRun()' could     corrupt the memory. Successful exploitation of this issue     may allow arbitrary code execution on the remote system.     Note this reportedly only affects 3.0.9. (MFSA 2009-23)

  - 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. (CVE-2009-2061)

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.
