Scientific Linux Security Update : thunderbird on SL4.x, SL5.x i386/x86_64

Description

Several flaws were found in the way Thunderbird processed certain malformed HTML mail content. A HTML mail message containing malicious content could cause Thunderbird to crash, or potentially execute arbitrary code as the user running Thunderbird. (CVE-2008-0412, CVE-2008-0413, CVE-2008-0415, CVE-2008-0419) Several flaws were found in the way Thunderbird displayed malformed HTML mail content. A HTML mail message containing specially crafted content could trick a user into surrendering sensitive information. (CVE-2008-0591, CVE-2008-0593) A flaw was found in the way Thunderbird handles certain chrome URLs. If a user has certain extensions installed, it could allow a malicious HTML mail message to steal sensitive session data. Note: this flaw does not affect a default installation of Thunderbird. (CVE-2008-0418) Note: JavaScript support is disabled by default in Thunderbird; the above issues are not exploitable unless JavaScript is enabled. A flaw was found in the way Thunderbird saves certain text files. If a remote site offers a file of type 'plain/text', rather than 'text/plain', Thunderbird will not show future 'text/plain' content to the user, forcing them to save those files locally to view the content. (CVE-2008-0592)
