Name of the Vulnerable Software and Affected Versions Thunderbird versions prior to 68.7.0 Firefox ESR versions prior to 68.7 Firefox versions prior to 75

Description The issue is related to an out of bounds write that could occur when processing an image larger than 4 GB in GMPDecodeData. This could potentially be exploited to run arbitrary code.
