For reference, these are the details of the original USN:

 Jonas Sicking discovered that under some circumstances persisted XUL
 attributes are associated with the wrong URL. A malicious web site
 could exploit this to execute arbitrary code with the privileges of
 the user. (MFSA 2006-35, CVE-2006-2775)

 Paul Nickerson discovered that content-defined setters on an object
 prototype were getting called by privileged UI code. It was
 demonstrated that this could be exploited to run arbitrary web script
 with full user privileges (MFSA 2006-37, CVE-2006-2776). A similar
 attack was discovered by moz_bug_r_a4 that leveraged SelectionObject
 notifications that were called in privileged context. (MFSA 2006-43,
 CVE-2006-2777)

 Mikolaj Habryn discovered a buffer overflow in the crypto.signText()
 function. By tricking a user to visit a site with an SSL certificate
 with specially crafted optional Certificate Authority name
 arguments, this could potentially be exploited to execute arbitrary
 code with the user's privileges. (MFSA 2006-38, CVE-2006-2778)

 The Mozilla developer team discovered several bugs that lead to
 crashes with memory corruption. These might be exploitable by
 malicious web sites to execute arbitrary code with the privileges of
 the user. (MFSA 2006-32, CVE-2006-2779, CVE-2006-2780, CVE-2006-2788)

 Chuck McAuley reported that the fix for CVE-2006-1729 (file stealing
 by changing input type) was not sufficient to prevent all variants of
 exploitation. (MFSA 2006-41, CVE-2006-2782)

 Masatoshi Kimura found a way to bypass web input sanitizers which
 filter out JavaScript. By inserting 'Unicode Byte-order-Mark (BOM)'
 characters into the HTML code (e. g. '<scr[BOM]ipt>'), these filters
 might not recognize the tags anymore, however, Firefox would still
 execute them since BOM markers are filtered out before processing the
 page. (MFSA 2006-42, CVE-2006-2783)

 Paul Nickerson noticed that the fix for CVE-2005-0752 (JavaScript
 privilege escalation on the plugins page) was not sufficient to
 prevent all variants of exploitation. (MFSA 2006-36, CVE-2006-2784)

 Paul Nickerson demonstrated that if an attacker could convince a user
 to right-click on a broken image and choose 'View Image' from the
 context menu then he could get JavaScript to run on a site of the
 attacker's choosing. This could be used to steal login cookies or
 other confidential information from the target site. (MFSA 2006-34,
 CVE-2006-2785)

 Kazuho Oku discovered various ways to perform HTTP response smuggling
 when used with certain proxy servers. Due to different interpretation
 of nonstandard HTTP headers in Firefox and the proxy server, a
 malicious web site can exploit this to send back two responses to one
 request. The ... [Please see the references for more information on the vulnerabilities]");
