NVD Description

Note: Versions mentioned in the description apply only to the upstream MozillaFirefox-branding-upstream package and not the MozillaFirefox-branding-upstream package as distributed by SLES.

Navigation events were not fully adhering to the W3C's "Navigation-Timing Level 2" draft specification in some instances for the unload event, which restricts access to detailed timing attributes to only be same-origin. This resulted in potential cross-origin information exposure of history through timing side-channel attacks. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1.
