The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200405-19
(Opera telnet URI handler file creation/truncation vulnerability)
The telnet URI handler in Opera does not check for leading '-'
characters in the host name. Consequently, a maliciously-crafted
telnet:// link may be able to pass options to the telnet program
itself. One example would be the following:
If MyFile exists in the user's home directory and the user clicking on
the link has write permissions to it, the contents of the file will be
overwritten with the output of the telnet trace information. If MyFile
does not exist, the file will be created in the user's home directory.
This exploit has two possible impacts. First, it may create new files
in the user's home directory. Second, and far more serious, it may
overwrite existing files that the user has write permissions to. An
attacker with some knowledge of a user's home directory might be able
to destroy important files stored within.
Disable the telnet URI handler from within Opera.
