Description Jan Lieskovsky 2010-10-08 09:47:04 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2010-3779 to
the following vulnerability:

Dovecot 1.2.x before 1.2.15 and 2.0.x before 2.0.beta2 grants the
admin permission to the owner of each mailbox in a non-public
namespace, which might allow remote authenticated users to bypass
intended access restrictions by changing the ACL of a mailbox, as
demonstrated by a symlinked shared mailbox.
