FileZilla 3.40.0 contains a denial of service vulnerability in the local search functionality that allows local attackers to crash the application by supplying a malformed path string. Attackers can trigger the crash by entering a crafted path containing 384 'A' characters followed by 'BBBB' and 'CCCC' sequences in the search directory field and initiating a local search operation.

Untrusted search path in FileZilla before 3.41.0-rc1 allows an attacker to gain privileges via a malicious 'fzsftp' binary in the user's home directory.
