does not check the length of the buffer in which the read data is
stored and only stops reading when a newline character is found.

A malicious NNTP server could use this bug to cause a buffer overflow
by sending an overly long response. Such an overflow allows arbitrary
code to be executed, with the privileges of the newspost process, on
the affected systems."

(Newspost: Buffer overflow vulnerability)

    Niels Heinen has discovered a buffer overflow in the socket_getline()
    function of Newspost, which can be triggered by providing long strings
    that do not end with a newline character.
  
Impact :

    A remote attacker could setup a malicious NNTP server and entice a
    Newspost user to post to it, leading to the crash of the Newspost
    process and potentially the execution of arbitrary code with the rights
    of the Newspost user.
  
Workaround :

    There is no known workaround at this time."
