Mozilla vulnerabilities

Details

Various flaws have been reported that allow an attacker to execute
arbitrary code with user privileges by tricking the user into opening
a malicious URL. (CVE-2006-2788, CVE-2006-3805, CVE-2006-3806,
CVE-2006-3807, CVE-2006-3809, CVE-2006-3811, CVE-2006-4565,
CVE-2006-4568, CVE-2006-4571)

A bug was found in the script handler for automatic proxy
configuration. A malicious proxy could send scripts which could
execute arbitrary code with the user's privileges. (CVE-2006-3808)

The NSS library did not sufficiently check the padding of PKCS #1 v1.5
signatures if the exponent of the public key is 3 (which is widely
used for CAs). This could be exploited to forge valid signatures
without the need of the secret key. (CVE-2006-4340)

Georgi Guninski discovered that even with JavaScript disabled, a
malicous email could still execute JavaScript when the message is
viewed, replied to, or forwarded by putting the script in a remote XBL
file loaded by the message. (CVE-2006-4570)
