CVE Ids        : CAN-2002-1581

A directory traversal vulnerability was discovered in mailreader
whereby remote attackers could view arbitrary files with the
privileges of the nph-mr.cgi process (by default, www-data) via
relative paths and a null byte in the configLanguage parameter.

For the current stable distribution (woody), this problem has been
fixed in version 2.3.29-5woody1.
