Ubuntu Security Notice USN-1721-1

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

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

- Ubuntu 12.10

Summary:

curl could be made to crash or run programs if it opened a malicious URL.

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

Details:

It was discovered that curl incorrectly handled SASL authentication when
communicating over POP3, SMTP or IMAP. If a user or automated system were
tricked into processing a specially crafted URL, an attacker could cause
a denial of service, or possibly execute arbitrary code. The default
compiler options for affected releases should reduce the vulnerability to a
denial of service.

Update instructions:

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

Ubuntu 12.10:
  libcurl3                        7.27.0-1ubuntu1.1
  libcurl3-gnutls                 7.27.0-1ubuntu1.1
  libcurl3-nss                    7.27.0-1ubuntu1.1

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