Ubuntu Security Notice USN-3262-1
20th April, 2017
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.04
Applications using curl could allow unintended access over the network.
- 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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 17.04:
- libcurl3-nss 7.52.1-4ubuntu1.1
- curl 7.52.1-4ubuntu1.1
- libcurl3-gnutls 7.52.1-4ubuntu1.1
- libcurl3 7.52.1-4ubuntu1.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
