Description Thomas Deutschmann (RETIRED) gentoo-dev 2016-11-28 23:16:42 UTC 
Redirection from an HTTP connection to a data: URL assigns the referring site's origin to the data: URL in some circumstances. This can result in same-origin violations against a domain if it loads resources from malicious sites. Cross-origin setting of cookies has been demonstrated without the ability to read them.

Note: This issue only affects Firefox 49 and 50.

Ebuild for 50.0.1 is in tree we do not keep stale builds so feel free to close as you desire.
Comment 2 Thomas Deutschmann (RETIRED) gentoo-dev 2016-11-29 01:48:43 UTC 
Dropping to ~1 because affected version were never stable.
