CVE-2021-29977

First published: Tue Jul 13 2021(Updated: )

Mozilla developers Andrew McCreight, Tyson Smith, Christian Holler, and Gabriele Svelto reported memory safety bugs present in Firefox 89. 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.
