fetchmail is vulnerable to denial of service. A flaw was found in fetchmail. When fetchmail is run in double verbose mode (β-v -vβ), it could crash upon receiving certain, malformed mail messages with long headers. A remote attacker could use this flaw to cause a denial of service if fetchmail was also running in daemon mode (β-dβ).
