CVE-2021-29970: Use-after-free in accessibility features of a document


Memory corruption bugs affecting Firefox, Firefox ESR, and Thunderbird. "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."


An out of bounds write in ANGLE could have allowed an attacker to corrupt memory leading to a potentially exploitable crash.
