Summary
Jakub Wilk discovered that dpkg did not correctly parse C-style filename quoting, allowing for paths to be traversed when unpacking a source package - leading to the creation of files outside the directory of the source being unpacked. The update to the stable distribution (wheezy) incorporates non-security changes that were targeted for the point release 7.5.
