fetchmailconf before 1.49 in fetchmail 6.2.0, 6.2.5 and 6.2.5.2 creates configuration files with insecure world-readable permissions, which allows local users to obtain sensitive information such as passwords.
Buffer overflow in the POP3 client in Fetchmail before 6.2.5.2 allows remote POP3 servers to cause a denial of service and possibly execute arbitrary code via long UIDL responses. NOTE: a typo in an advisory accidentally used the wrong CVE identifier for the Fetchmail issue. This is the correct identifier.
