+ cURL is a command line tool for transferring files with URL syntax,

+ <description>
+ <p>
+ 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.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ 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.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All cURL users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-misc/curl-7.19.6"</code>
