Multiple unspecified vulnerabilities in Dovecot before 1.0beta3 allow remote attackers to cause a denial of service (application crash or hang) via unspecified vectors involving (1) "potential hangs" in the APPEND command and "potential crashes" in (2) dovecot-auth and (3) imap/pop3-login. NOTE: vector 2 might be related to a double free vulnerability.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
