This revision of dpkg instead refuses to process patches with C-style filename quoting altogether. For reference, the original text of DSA-2915-1 is reproduced below: 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. For the oldstable distribution (squeeze), this problem has been fixed in version 1.15.10. For the stable distribution (wheezy), this problem has been fixed in version 1.16.14. For the testing distribution (jessie), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 1.17.9. We recommend that you upgrade your dpkg packages.
