#CVE-2019-11744: XSS by breaking out of title and textarea elements using innerHTML

Reporter
    Rakesh Mane
Impact
    high

Description

Some HTML elements, such as <title> and <textarea>, can contain literal angle brackets without treating them as markup. It is possible to pass a literal closing tag to .innerHTML on these elements, and subsequent content after that will be parsed as if it were outside the tag. This can lead to XSS if a site does not filter user input as strictly for these elements as it does for other elements.

#CVE-2019-11743: Cross-origin access to unload event attributes

Reporter
    Yoav Weiss
Impact
    moderate

Description

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.

#CVE-2019-11740: Memory safety bugs fixed in Firefox 69, Firefox ESR 68.1, Firefox ESR 60.9, Thunderbird 68.1, and Thunderbird 60.9

Reporter

Impact
    high

Description

Mozilla developers and community members Tyson Smith and Nathan Froyd reported memory safety bugs present in Firefox 68, Firefox ESR 68, Firefox 60.8, Thunderbird 68, and Thunderbird 60.8. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code.
