Ubuntu Security Notice USN-2167-1

curl vulnerabilities
============================================================================

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

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

Summary:

Several security issues were fixed in curl.

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

Details:

Steve Holme discovered that libcurl incorrectly reused wrong connections
when using protocols other than HTTP and FTP. This could lead to the use of
unintended credentials, possibly exposing sensitive information.
(CVE-2014-0138)

Richard Moore discovered that libcurl incorrectly validated wildcard SSL
certificates that contain literal IP addresses. An attacker could possibly
exploit this to perform a man in the middle attack to view sensitive
information or alter encrypted communications. (CVE-2014-0139)

Update instructions:

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