Synopsis: Important: thunderbird security update Advisory ID: SLSA-2015:0047-1 Issue Date: 2015-01-13 CVE Numbers: CVE-2014-8634 CVE-2014-8638 CVE-2014-8639 -- Two flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2014-8634, CVE-2014-8639) It was found that the Beacon interface implementation in Thunderbird did not follow the Cross-Origin Resource Sharing (CORS) specification. A web page containing malicious content could allow a remote attacker to conduct a Cross-Site Request Forgery (XSRF) attack. (CVE-2014-8638) Note: All of the above issues cannot be exploited by a specially crafted HTML mail message as JavaScript is disabled by default for mail messages. They could be exploited another way in Thunderbird, for example, when viewing the full remote content of an RSS feed. After installing the update, Thunderbird must be restarted for the changes to take effect. -- SL5 x86_64 thunderbird-31.4.0-1.el5_11.x86_64.rpm thunderbird-debuginfo-31.4.0-1.el5_11.x86_64.rpm i386 thunderbird-31.4.0-1.el5_11.i386.rpm thunderbird-debuginfo-31.4.0-1.el5_11.i386.rpm SL6 x86_64 thunderbird-31.4.0-1.el6_6.x86_64.rpm thunderbird-debuginfo-31.4.0-1.el6_6.x86_64.rpm i386 thunderbird-31.4.0-1.el6_6.i686.rpm thunderbird-debuginfo-31.4.0-1.el6_6.i686.rpm - Scientific Linux Development Team
