CVE-2016-1947 Mozilla: Application Reputation service disabled in Firefox 43 (MFSA 2016-11)
Last modified: 2016-01-26 23:51:16 EST
Mozilla developer FranÃ§ois Marier reported that the Firefox was unable to reach the Application Reputation service due to a bug introduced in Firefox 43, disabling the ability to warn against potentially malicious downloads. Other parts of the Safe Browsing feature, for example the warnings about phishing and malicious sites, continued to function.
This issue was caused by a flaw introduced in Firefox 43. Earlier versions were not affected by this issue.
Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges FranÃ§ois Marier as the original reporter.
This issue does not affect the version of firefox and thunderbird as shipped with Red Hat Enterprise Linux 5, 6 and 7.
