Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200909-20
(cURL: Certificate validation error)

Scott Cantor reported that cURL does not properly handle fields in
X.509 certificates that contain an ASCII NUL (\\0) character.
Specifically, the processing of such fields is stopped at the first
occurence of a NUL character. This type of vulnerability was recently
discovered by Dan Kaminsky and Moxie Marlinspike.

Impact :

A remote attacker might employ a specially crafted X.509 certificate
(that for instance contains a NUL character in the Common Name field)
to conduct man-in-the-middle attacks.

Workaround :

There is no known workaround at this time.

# emerge --ask --oneshot --verbose '>=net-misc/curl-7.19.6'
