Package: sympa
Version: 6.0.1+dfsg-4
Severity: grave
Sympa versions <6.1.11 have a severe security issue where any user can
download or delete the archives of a mailing list if they know the name
of the list.
Debian has been tracking it at
http://security-tracker.debian.org/tracker/CVE-2012-2352
I'm attaching a patch (taken from upstream commit:
https://sourcesup.renater.fr/scm/viewvc.php/branches/sympa-6.0-branch/wwsympa/wwsympa.fcgi.in?root=sympa&pathrev=7358
) that fixes the problem
