Ubuntu Security Notice USN-2048-1
December 05, 2013

curl vulnerability
==========================================================================

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

- Ubuntu 13.10
- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Fraudulent security certificates could allow sensitive information to
be exposed when accessing the Internet.

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

Details:

Scott Cantor discovered that libcurl incorrectly verified CN and SAN name
fields when digital signature verification was disabled. When libcurl is
being used in this uncommon way by specific applications, an attacker could
exploit this to perform a man in the middle attack to view sensitive
information or alter encrypted communications.

Update instructions:

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

Ubuntu 13.10:
libcurl3 7.32.0-1ubuntu1.1

Ubuntu 13.04:
libcurl3 7.29.0-1ubuntu3.3

Ubuntu 12.10:
libcurl3 7.27.0-1ubuntu1.5

Ubuntu 12.04 LTS:
libcurl3 7.22.0-3ubuntu4.4

Ubuntu 10.04 LTS:
libcurl3 7.19.7-1ubuntu1.4

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