========================================================================== Ubuntu Security Notice USN-1143-1 June 02, 2011
dovecot vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS
Summary:
An attacker could send a crafted email message that could disrupt email service.
Software Description: - dovecot: IMAP and POP3 email server
Details:
It was discovered that the message header parser in Dovecot did not properly handle '\0' characters in header names. This could allow a remote attacker to cause a denial of service through a crafted email message by crashing the Dovecot daemon or corrupting mailboxes.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.04: dovecot-common 1:1.2.15-3ubuntu2.1
Ubuntu 10.10: dovecot-common 1:1.2.12-1ubuntu8.2
Ubuntu 10.04 LTS: dovecot-common 1:1.2.9-1ubuntu6.4
In general, a standard system update will make all the necessary changes.
