The remote host is affected by the vulnerability described in GLSA-200403-10 (Fetchmail 6.2.5 fixes a remote DoS)

Fetchmail versions 6.2.4 and earlier can be crashed by sending a     specially crafted email to a Fetchmail user. This problem occurs because     Fetchmail does not properly allocate memory for long lines in an incoming     email.

Workaround :

While a workaround is not currently known for this issue, all users are advised to upgrade to the latest version of Fetchmail.
