sympa - authorization bypass

Several vulnerabilities have been discovered in Sympa, a mailing list
manager, that allow to skip the scenario-based authorization
mechanisms. This vulnerability allows to display the archives
management page, and download and delete the list archives by
unauthorized users.

For the stable distribution (squeeze), this problem has been fixed in
version 6.0.1+dfsg-4+squeeze1.

For the testing distribution (wheezy), this problem will be fixed
soon.

For the unstable distribution (sid), this problem has been fixed in
version 6.1.11~dfsg-2.

We recommend that you upgrade your sympa packages.
