Debian: New qpopper packages fix arbitrary file overwriting

Two bugs have been discovered in qpopper, an enhanced Post Office Protocol (POP3) server. Jens Steube discovered that while processing local files owned or provided by a normal user privileges weren't dropped, which could lead to the overwriting or creation of arbitrary files as root. The upstream developers noticed that qpopper could be tricked to creating group- or world-writable files. Fixed packages are available from security.debian.org.
