FileZilla is an open source FTP client.
It was discovered that FileZilla uses an untrusted search path.
An attacker could use a malicious binary to escalate privileges.
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-3.47.2.1"
