Discussion

FileZilla Server SSL/TLS Unspecified Buffer Overflow Denial Of Service Vulnerability

FileZilla Server is prone to a denial-of-service vulnerability because it fails to adequately validate data before copying it into an insufficiently sized buffer.

Attackers can exploit this issue to cause denial-of-service conditions. Given the nature of this issue, remote code execution may also be possible, but this has not been confirmed.

Versions prior to FileZilla Server 0.9.31 are vulnerable.
