Security News > 2020 > December > Firefox Patches Critical Mystery Bug, Also Impacting Google Chrome
A Mozilla Foundation update to the Firefox web browser, released Tuesday, tackles one critical vulnerability and a handful of high-severity bugs.
The specific critical bug in Firefox was also highlighted earlier this month in Google's Chrome browser security update, where it was rated as a high-severity flaw.
The Firefox and Chrome bug in question is still not fully described by either browser maker, and is only listed as a memory bug.
WASM is supported in Mozilla Firefox and Apple Safari, even though both do not use Google's V8. Some clues as to the nature of the bug can be derived by the fact the bug impacts both the Firefox and Chrome browser - the common denominator is WASM. In addition, a 2018 analysis of WASM and V8 bugs warned of possible security issues.
Credited for finding the bug is bug hunter André Bargull, who originally reported the bug on November 23, according to Google.
