USN-382-1: Thunderbird vulnerabilities

21 November 2006

Thunderbird vulnerabilities



USN-352-1 fixed a flaw in the verification of PKCS certificate
signatures. Ulrich Kuehn discovered a variant of the original attack
which the original fix did not cover. (CVE-2006-5462)

Various flaws have been reported that allow an attacker to execute
arbitrary code with user privileges by tricking the user into opening a
malicious email containing JavaScript. Please note that JavaScript is
disabled by default for emails, and it is not recommended to enable it.
(CVE-2006-5463, CVE-2006-5464, CVE-2006-5747, CVE-2006-5748)
