Vulnerability from github – Published: 2022-05-24 17:43 – Updated: 2022-05-28 00:00

Details

The developer page about:memory has a Measure function for exploring what object types the browser has allocated and their sizes. When this function was invoked we incorrectly called the sizeof function, instead of using the API method that checks for invalid pointers. This vulnerability affects Firefox < 86.

Severity ?

6.5 (Medium)
