Detail
| Multiple vulnerabilities was discovered and corrected in dovecot: 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 (CVE-2010-3779). Dovecot 1.2.x before 1.2.15 allows remote authenticated users to cause a denial of service (master process outage) by simultaneously disconnecting many (1) IMAP or (2) POP3 sessions (CVE-2010-3780). The ACL plugin in Dovecot 1.2.x before 1.2.13 propagates INBOX ACLs to newly created mailboxes in certain configurations, which might allow remote attackers to read mailboxes that have unintended weak ACLs (CVE-2010-3304). plugins/acl/acl-backend-vfile.c in Dovecot 1.2.x before 1.2.15 and 2.0.x before 2.0.5 interprets an ACL entry as a directive to add to the permissions granted by another ACL entry, instead of a directive to replace the permissions granted by another ACL entry, in certain circumstances involving the private namespace of a user, which allows remote authenticated users to bypass intended access restrictions via a request to read or modify a mailbox (CVE-2010-3706). plugins/acl/acl-backend-vfile.c in Dovecot 1.2.x before 1.2.15 and 2.0.x before 2.0.5 interprets an ACL entry as a directive to add to the permissions granted by another ACL entry, instead of a directive to replace the permissions granted by another ACL entry, in certain circumstances involving more specific entries that occur after less specific entries, which allows remote authenticated users to bypass intended access restrictions via a request to read or modify a mailbox (CVE-2010-3707). This advisory provides dovecot 1.2.15 which is not vulnerable to these issues |

| Title: | USN-1059-1 -- dovecot vulnerabilities | ||
| Description: | It was discovered that the ACL plugin in Dovecot would incorrectly propagate ACLs to new mailboxes. A remote authenticated user could possibly read new mailboxes that were created with the wrong ACL. It was discovered that the ACL plugin in Dovecot would incorrectly merge ACLs in certain circumstances. A remote authenticated user could possibly bypass intended access restrictions and gain access to mailboxes. It was discovered that the ACL plugin in Dovecot would incorrectly grant the admin permission to owners of certain mailboxes. A remote authenticated user could possibly bypass intended access restrictions and gain access to mailboxes. It was discovered that Dovecot incorrecly handled the simultaneous disconnect of a large number of sessions. A remote authenticated user could use this flaw to cause Dovecot to crash, resulting in a denial of service | ||

Dovecot contains a flaw related to 'plugins/acl/acl-backend-vfile.c' interpreting an ACL permissions entry which may involve a user's private namespace and is of the same type as a previous ACL entry as an addition rather than a replacement. This may allow a remote authenticated attacker to use a request to read or modify a mailbox to bypass intended access restrictions. |

Dovecot contains a flaw related to 'plugins/acl/acl-backend-vfile.c' interpreting a less specific ACL permissions entry of the same type as a previous more specific ACL entry as an addition rather than a replacement. This may allow a remote authenticated attacker to use a request to read or modify a mailbox to bypass intended access restrictions. |

Dovecot contains a flaw related to the ACL plugin granting admin permissions to mailbox owners in non-public namespaces. This may allow a remote authenticated attacker to bypass intended access restrictions by changing a mailbox's ACL. |
| 68512 | Dovecot IMAP / POP3 Session Disconnect Master Process Outage Remote DoS Dovecot contains a flaw that may allow a remote denial of service.
