Name of the Vulnerable Software and Affected Versions Firefox versions prior to 64 Firefox ESR versions prior to 60.4 Thunderbird versions prior to 60.4

Description The issue is related to an integer overflow that can lead to an out-of-bounds write in memory. This can be exploited by a remote attacker to potentially write data outside the boundaries of a buffer. The vulnerability is associated with buffer size calculations for images when an unchecked raw value is used instead of a validated value.

Recommendations For Firefox versions prior to 64, update to version 64 or later to resolve the issue. For Firefox ESR versions prior to 60.4, update to version 60.4 or later to resolve the issue. For Thunderbird versions prior to 60.4, update to version 60.4 or later to resolve the issue.
