+dpkg: Security Advisory - CVE-2014-3127
+
+commit a12eb58959d0a10584a428f4a3103a49204c410f upstream
+
+dpkg 1.15.9 on Debian squeeze introduces support for the "C-style
+encoded filenames" feature without recognizing that the squeeze patch
+program lacks this feature, which triggers an interaction error that
+allows remote attackers to conduct directory traversal attacks and
+modify files outside of the intended directories via a crafted source
+package.
+
+NOTE: this can be considered a release engineering problem in the
+effort to fix CVE-2014-0471.
+
+Upstream-Status: Backport
