Debian: New rlpr packages fix multiple vulnerabilities

jaguar (at) felinemenace.org discovered a format string vulnerability in rlpr, a utility for lpd printing without using /etc/printcap. While investigating this vulnerability, a buffer overflow was also discovered in related code. By exploiting one of these vulnerabilities, a local or remote user could potentially cause arbitrary code to be executed with the privileges of 1) the rlprd process (remote), or 2) root (local). Fixed packages are available from security.debian.org.
