Description

Gerfried Fuchs uploaded new packages for dovecot which fixed the following security problems:

CVE-2008-4577, Debian Bug #502967

The ACL plugin in Dovecot before 1.1.4 treats negative access rights as if they are positive access rights, which allows attackers to bypass intended access restrictions.

Debian Bug #506031

A flaw in the handling of script names in ManageSieve offered the posibility to read and edit script files of other virtual users with the same system uid.

For the etch-backports distribution the problems have been fixed in version 1.0.15-2.3~bpo40+1.

For the lenny and sid distributions the problems have been fixed in version 1.0.15-2.3.

Upgrade instructions

If you don't use pinning (see [1]) you have to update the packages manually via "apt-get -t etch-backports install <packagelist>" with the packagelist of your installed packages affected by this update. [1] <http://backports.org/dokuwiki/doku.php?id=instructions>

We recommend to pin the backports repository to 200 so that new versions of installed backports will be installed automatically:

Package: * Pin: release a=etch-backports Pin-Priority: 200
