Details follow:
Martijn Wargers, Josh Soref, Jesse Ruderman, and Ehsan Akhgari discovered
flaws in the browser engine of Firefox. If a user were tricked into viewing
a malicious website, a remote attacker could cause a denial of service or
possibly execute arbitrary code with the privileges of the user invoking
the program. (CVE-2010-0173, CVE-2010-0174)
It was discovered that Firefox could be made to access previously freed
memory. If a user were tricked into viewing a malicious website, a remote
attacker could cause a denial of service or possibly execute arbitrary code
with the privileges of the user invoking the program. (CVE-2010-0175,
CVE-2010-0176, CVE-2010-0177)
Paul Stone discovered that Firefox could be made to change a mouse click
into a drag and drop event. If the user could be tricked into performing
this action twice on a crafted website, an attacker could execute
arbitrary JavaScript with chrome privileges. (CVE-2010-0178)
It was discovered that the XMLHttpRequestSpy module as used by the Firebug
add-on could be used to escalate privileges within the browser. If the user
had the Firebug add-on installed and were tricked into viewing a malicious
website, an attacker could potentially run arbitrary JavaScript.
(CVE-2010-0179)
Henry Sudhof discovered that an image tag could be used as a redirect to
a mailto: URL to launch an external mail handler. (CVE-2010-0181)

checks on XML content. An attacker could exploit this to bypass security
policies to load certain resources. (CVE-2010-0182)
