NSS has shown timing differences when performing DSA signatures, which was exploitable and could eventually leak private keys.
When browsing a malicious page, a race condition in our SharedWorkerService could occur and lead to a potentially exploitable crash.
Mozilla Developer Iain Ireland discovered a missing type check during unboxed objects removal, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code.
Mozilla Developer Nicolas Silva found that when using WebRender, Firefox would under certain conditions leak arbitrary GPU memory to the visible screen. The leaked memory content was visible to the user, but not observable from web content.
When browsing a document hosted on an IP address, an attacker could insert certain characters to flip domain and path information in the address bar.
When using certain blank characters in a URL, they where incorrectly rendered as spaces instead of an encoded URL.
Mozilla developers Tom Tung and Karl Tomlinson reported memory safety bugs present in Firefox 76 and Firefox ESR 68.8. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
Mozilla developers :Gijs (he/him), Randell Jesup reported memory safety bugs present in Firefox 76. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
