Ubuntu Security Notice USN-2183-2
May 01, 2014

dpkg vulnerability
==========================================================================

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

- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

A malicious source package could write files outside the unpack directory.

Software Description:
- dpkg: Debian package management system

Details:

USN-2183-1 fixed a vulnerability in dpkg. Javier Serrano Polo discovered
that the fix introduced a vulnerability in releases with an older version
of the patch utility. This update fixes the problem.

Original advisory details:

Jakub Wilk discovered that dpkg incorrectly certain paths and symlinks when
unpacking source packages. If a user or an automated system were tricked
into unpacking a specially crafted source package, a remote attacker could
modify files outside the target unpack directory, leading to a denial of
service or potentially gaining access to the system.

Update instructions:

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

Ubuntu 14.04 LTS:
libdpkg-perl 1.17.5ubuntu5.2

Ubuntu 13.10:
libdpkg-perl 1.16.12ubuntu1.2

Ubuntu 12.10:
libdpkg-perl 1.16.7ubuntu6.2

Ubuntu 12.04 LTS:
libdpkg-perl 1.16.1.2ubuntu7.4

Ubuntu 10.04 LTS:
dpkg-dev 1.15.5.6ubuntu4.8

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

openjdk-6 vulnerabilities
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in OpenJDK 6.

Software Description:
- openjdk-6: Open Source Java implementation

Details:

Several vulnerabilities were discovered in the OpenJDK JRE related to
information disclosure, data integrity and availability. An attacker could
exploit these to cause a denial of service or expose sensitive data over
the network. (CVE-2014-0429, CVE-2014-0446, CVE-2014-0451, CVE-2014-0452,
CVE-2014-0456, CVE-2014-0457, CVE-2014-0458, CVE-2014-0461, CVE-2014-0462,
CVE-2014-2397, CVE-2014-2405, CVE-2014-2412, CVE-2014-2414, CVE-2014-2421,
CVE-2014-2423, CVE-2014-2427)

Two vulnerabilities were discovered in the OpenJDK JRE related to
information disclosure and data integrity. An attacker could exploit these
to expose sensitive data over the network. (CVE-2014-0453, CVE-2014-0460)

A vulnerability was discovered in the OpenJDK JRE related to availability.
An attacker could exploit this to cause a denial of service.
(CVE-2014-0459)

Jakub Wilk discovered that the OpenJDK JRE incorrectly handled temporary
files. A local attacker could possibly use this issue to overwrite
arbitrary files. In the default installation of Ubuntu, this should be
prevented by the Yama link restrictions. (CVE-2014-1876)

A vulnerability was discovered in the OpenJDK JRE related to data
integrity. (CVE-2014-2398)

A vulnerability was discovered in the OpenJDK JRE related to information
disclosure. An attacker could exploit this to expose sensitive data over
the network. (CVE-2014-2403)

Update instructions:

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

Ubuntu 12.04 LTS:
icedtea-6-jre-cacao 6b31-1.13.3-1ubuntu1~0.12.04.2
icedtea-6-jre-jamvm 6b31-1.13.3-1ubuntu1~0.12.04.2
