Multiple vulnerabilities were reported in Mozilla Thunderbird. A remote user can execute arbitrary code on the target system. A remote user can bypass security controls on the target system. A remote user can obtain potentially sensitive information.|
A remote user can create specially crafted HTML that, when loaded by the target user, will trigger a memory corruption error and execute arbitrary code on the target system [CVE-2015-2724, CVE-2015-2725, CVE-2015-2726, CVE-2015-2734, CVE-2015-2735, CVE-2015-2736, CVE-2015-2737, CVE-2015-2738, CVE-2015-2739, CVE-2015-2740]. The code will run with the privileges of the target user.
A remote user can trigger a use-after-free memory error in CSPService::ShouldLoad() when a Content Policy modifies the Document Object Model (DOM) to remove a DOM object [CVE-2015-2731].
A remote user can trigger a use-after-free memory error when using XMLHttpRequest in conjunction with shared or dedicated workers [CVE-2015-2722, CVE-2015-2733].
When an error that may be overridden occurs, key pinning checks may be missed [CVE-2015-2741].
A remote user that can conduct a man-in-the-middle attack can cause the target system to downgrade the Diffie-Hellman algorithm to 512-bit export-grade cryptography [CVE-2015-4000]. The remote user may then be able to decrypt the connection.
This vulnerability resides in the TLS protocol and not in the specific TLS implementation, but the vulnerability is exposed because the target system supports export-grade ciphers. This attack is known as the "Logjam" attack.
A remote user (server) can exploit a flaw in Network Security Services (NSS) by failing to send the ServerKeyExchange message as part of a ECDHE_ECDSA exchange to cause the target NSS client to use the EC key from the ECDSA certificate, a downgraded exchange [CVE-2015-2721].
