Tobias Grützmacher discovered that a Debian-provided CRON script in dspam, a statistical spam filter, included a database password on the command line. This allowed a local attacker to read the contents of the dspam database, such as emails.
The old stable distribution (sarge) does not contain the dspam package.
For the stable distribution (etch), this problem has been fixed in version 3.6.8-5etch1.
For the unstable distribution (sid), this problem has been fixed in version 3.6.8-5.1.
We recommend that you upgrade your dspam package.
