Firefox URL parsing routines. If a user were tricked into opening a
crafted hyperlink, an attacker could overflow a stack buffer and
execute arbitrary code. (CVE-2008-0016)

It was discovered that the same-origin check in Firefox could be
bypassed. If a user were tricked into opening a malicious website, an
attacker may be able to execute JavaScript in the context of a
different website. (CVE-2008-3835)

Several problems were discovered in the JavaScript engine. This could
allow an attacker to execute scripts from page content with chrome
privileges. (CVE-2008-3836)

Paul Nickerson discovered Firefox did not properly process mouse click
events. If a user were tricked into opening a malicious web page, an
attacker could move the content window, which could potentially be
used to force a user to perform unintended drag and drop operations.

Several problems were discovered in the browser engine. This could
allow an attacker to execute code with chrome privileges.
(CVE-2008-4058, CVE-2008-4059, CVE-2008-4060)

Drew Yao, David Maciejak and other Mozilla developers found several
problems in the browser engine of Firefox. If a user were tricked into
opening a malicious web page, an attacker could cause a denial of
service or possibly execute arbitrary code with the privileges of the
user invoking the program. (CVE-2008-4061, CVE-2008-4062,
CVE-2008-4063, CVE-2008-4064)

processing certain BOM characters. An attacker could exploit this to
bypass script filters and perform cross-site scripting attacks.

user were tricked into opening a malicious web page, an attacker could
bypass script filtering and perform cross-site scripting attacks.

Boris Zbarsky and Georgi Guninski independently discovered flaws in
the resource: protocol. An attacker could exploit this to perform
directory traversal, read information about the system, and prompt the
user to save information in a file. (CVE-2008-4067, CVE-2008-4068)

Billy Hoffman discovered a problem in the XBM decoder. If a user were
tricked into opening a malicious web page or XBM file, an attacker may
be able to cause a denial of service via application crash.
