"The remote host is affected by the vulnerability described in GLSA-200701-20
(Centericq: Remote buffer overflow in LiveJournal handling)

    When interfacing with the LiveJournal service, Centericq does not
    appropriately allocate memory for incoming data, in some cases creating
    a buffer overflow.
  
Impact :

    An attacker could entice a user to connect to an unofficial LiveJournal
    server causing Centericq to read specially crafted data from the
    server, which could lead to the execution of arbitrary code with the
    rights of the user running Centericq.
  
Workaround :

    There is no known workaround at this time."
