Description

Updated firefox & thunderbird packages fix security vulnerabilities Updated nss, firefox, and thunderbird packages fix security vulnerabilities: In the QuickDER decoder in NSS before 3.17.3, ASN.1 DER decoding of lengths is too permissive, allowing undetected smuggling of arbitrary data (CVE-2014-1569). Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox or Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running it (CVE-2014-1587, CVE-2014-1590, CVE-2014-1592, CVE-2014-1593). A flaw was found in the Alarm API, which could allow applications to schedule actions to be run in the future. A malicious web application could use this flaw to bypass the same-origin policy (CVE-2014-1594). This update adds support for the TLS Fallback Signaling Cipher Suite Value (TLS_FALLBACK_SCSV) in NSS, which can be used to prevent protocol downgrade attacks against applications which re-connect using a lower SSL/TLS protocol version when the initial connection indicating the highest supported protocol version fails. This can prevent a forceful downgrade of the communication to SSL 3.0, mitigating CVE-2014-3566, also known as POODLE. SSL 3.0 support has also been disabled by default in this Firefox and Thunderbird update, further mitigating POODLE.
