curl vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.04


Applications using curl could allow unintended access over the network.

Software Description:
- curl: HTTP, HTTPS, and FTP client and client libraries


It was discovered that curl incorrectly handled client certificates when
resuming a TLS session. A remote attacker could use this to hijack a
previously authenticated connection.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 17.04:
curl 7.52.1-4ubuntu1.1
libcurl3 7.52.1-4ubuntu1.1
libcurl3-gnutls 7.52.1-4ubuntu1.1
libcurl3-nss 7.52.1-4ubuntu1.1

In general, a standard system update will make all the necessary changes.
