CVE-2017-5444

Name of the Vulnerable Software and Affected Versions Thunderbird versions prior to 52.1 Firefox ESR versions prior to 52.1 Firefox versions prior to 53 Firefox ESR versions prior to 45.9

Description A buffer overflow vulnerability occurs while parsing "application/http-index-format" format content when the header contains improperly formatted data, allowing for an out-of-bounds read of data from memory. The vulnerability is related to the implementation of the nsDirIndexParser::ParseData method in the nsDirIndexParser.cpp file, which can lead to a buffer overflow in memory. This issue can be exploited by a remote attacker to gain access to protected information.
