Description
A flaw was found in Mozilla. The Mozilla Foundation Security Advisory described the issue in which Mozilla developers Timothy Nikkel, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 110 and ESR 102.8. 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.
