Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 71
Firefox ESR versions prior to 68.3
Thunderbird versions prior to 68.3
Description
The issue is related to a buffer out of bounds write in memory when using a block cipher for encryption. If a call to
NSC EncryptUpdate was made with data smaller than the block size, it could result in a small out of bounds write, potentially causing heap corruption and a crash. This could allow a remote attacker to gain unauthorized access to information and compromise its integrity and availability.Recommendations
For Firefox versions prior to 71, update to version 71 or later.
For Firefox ESR versions prior to 68.3, update to version 68.3 or later.
For Thunderbird versions prior to 68.3, update to version 68.3 or later.
