Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200503-20
(curl: NTLM response buffer overflow)

curl fails to properly check boundaries when handling NTLM
authentication.

Impact :

With a malicious server an attacker could send a carefully crafted
NTLM response to a connecting client leading to the execution of
arbitrary code with the permissions of the user running curl.

Workaround :

Disable NTLM authentication by not using the --anyauth or --ntlm
options.
