FileZilla is an open source FTP client.
FileZilla is affected by the same vulnerability as reported in “GLSA 201703-03” because the package included a vulnerable copy of PuTTY. Please read the GLSA for PuTTY referenced below for details.
A remote attacker, utilizing the SSH agent forwarding of an SSH server, could execute arbitrary code with the privileges of the user running FileZilla or cause a Denial of Service condition.
There is no known workaround at this time.
All FileZilla users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-ftp/filezilla-3.25.2"
