Ubuntu Security Notice USN-1569-1
September 17, 2012

php5 vulnerabilities
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

Several security issues were fixed in PHP.

Software Description:
- php5: HTML-embedded scripting language interpreter

Details:

It was discovered that PHP incorrectly handled certain character sequences
when applying HTTP response-splitting protection. A remote attacker could
create a specially-crafted URL and inject arbitrary headers.
(CVE-2011-1398, CVE-2012-4388)

It was discovered that PHP incorrectly handled directories with a large
number of files. This could allow a remote attacker to execute arbitrary
code with the privileges of the web server, or to perform a denial of
service. (CVE-2012-2688)

It was discovered that PHP incorrectly parsed certain PDO prepared
statements. A remote attacker could use this flaw to cause PHP to crash,
leading to a denial of service. (CVE-2012-3450)

Update instructions:

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

Ubuntu 12.04 LTS:
php5 5.3.10-1ubuntu3.4

Ubuntu 11.10:
php5 5.3.6-13ubuntu3.9

Ubuntu 11.04:
php5 5.3.5-1ubuntu7.11

Ubuntu 10.04 LTS:
php5 5.3.2-1ubuntu4.18

Ubuntu 8.04 LTS:
php5 5.2.4-2ubuntu5.26

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

==========================================================================
Ubuntu Security Notice USN-1570-1
September 17, 2012

gnupg, gnupg2 vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

GnuPG could be tricked into downloading a different key when downloading
from a key server.

Software Description:
- gnupg: GNU privacy guard - a free PGP replacement
- gnupg2: GNU privacy guard - a free PGP replacement

Details:

It was discovered that GnuPG used a short ID when downloading keys from a
keyserver, even if a long ID was requested. An attacker could possibly use
this to return a different key with a duplicate short key id.

Update instructions:

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

Ubuntu 12.04 LTS:
gnupg 1.4.11-3ubuntu2.1
gnupg2 2.0.17-2ubuntu2.12.04.1

Ubuntu 11.10:
gnupg 1.4.11-3ubuntu1.11.10.1
gnupg2 2.0.17-2ubuntu2.11.10.1

Ubuntu 11.04:
gnupg 1.4.11-3ubuntu1.11.04.1
gnupg2 2.0.14-2ubuntu1.2

Ubuntu 10.04 LTS:
gnupg 1.4.10-2ubuntu1.1
gnupg2 2.0.14-1ubuntu1.4

Ubuntu 8.04 LTS:
gnupg 1.4.6-2ubuntu5.1
gnupg2 2.0.7-1ubuntu0.2

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