"The remote host is affected by the vulnerability described in GLSA-200406-01
(Ethereal: Multiple security problems)

    There are multiple vulnerabilities in versions of Ethereal earlier than
    0.10.4, including:
    A buffer overflow in the MMSE dissector.
    Under specific conditions a SIP packet could make Ethereal
    crash.
    The AIM dissector could throw an assertion, causing Ethereal to
    crash.
    The SPNEGO dissector could dereference a NULL pointer, causing a
    crash.
  
Impact :

    An attacker could use these vulnerabilities to crash Ethereal or even
    execute arbitrary code with the permissions of the user running
    Ethereal, which could be the root user.
  
Workaround :

    For a temporary workaround you can disable all affected protocol
    dissectors by selecting Analyze->Enabled Protocols... and deselecting
    them from the list. However, it is strongly recommended to upgrade to
    the latest stable release."
