Detail

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

- Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS

Summary:

dpkg could be tricked into bypassing source package signature checks.

Software Description: - dpkg: Debian package management system

Details:

Jann Horn discovered that dpkg incorrectly validated signatures when extracting local source packages. If a user or an automated system were tricked into unpacking a specially crafted source package, a remote attacker could bypass signature verification checks.

Update instructions:

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

Ubuntu 14.10:
libdpkg-perl 1.17.13ubuntu1.1

Ubuntu 14.04 LTS:
libdpkg-perl 1.17.5ubuntu5.4

Ubuntu 12.04 LTS:
libdpkg-perl 1.16.1.2ubuntu7.6

Ubuntu 10.04 LTS:
dpkg-dev 1.15.5.6ubuntu4.10

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