This bug was fixed in the package dpkg - 1.15.5.6ubuntu2
---------------
dpkg (1.15.5.6ubuntu2) lucid; urgency=high
* Backport from upstream:
- Use FIEMAP when available (on Linux based systems) to sort the .list
files loading order. With a cold cache it improves up to a 70%.
Thanks to Morten Hustveit <mor...@debian.org>. LP: #442114
- Call fsync(2) after writing files on disk, to get the atomicity
guarantees when doing rename(2). Based on a patch by Jean-Baptiste
Lallement <jeanbaptiste.lallem...@gmail.com>.
Closes: #430958, LP: #512096
* Security fixes by Raphaël Hertzog, also backported from upstream
(CVE-2010-0396):
- Modify dpkg-source to error out when it would apply patches containing
insecure paths (with "/../") and also error out when it would apply a
patch through a symlink. Those checks are required as patch will
happily modify files outside of the target directory and unpacking a
source package should not be able to have any side-effect outside of
the target directory. LP: #532445
- Also error out when the quilt series contains a path with "/../" as
this can cause patch to create files outside of the source package due
to the -B .pc/$path option that it gets.
