Name of the Vulnerable Software and Affected Versions
Thunderbird versions prior to 52.1

Description
The issue is related to the parsing of "application/http-index-format" format content, where uninitialized values are used to create an array, potentially allowing the reading of uninitialized memory into the affected arrays. This could enable a remote attacker to access protected information due to a lack of checking during array indexing in the nsDirIndexParser::ParseFormat method.
Recommendations
For Thunderbird versions prior to 52.1, update to version 52.1 or later.
For Firefox ESR versions prior to 52.1, update to version 52.1 or later.
For Firefox ESR versions prior to 45.9, update to version 45.9 or later.
For Firefox versions prior to 53, update to version 53 or later.
