"The version of Pidgin installed on the remote Windows host is prior to 
2.11.0. It is, therefore, affected by multiple vulnerabilities :

  - A NULL pointer dereference flaw exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    crafted MXIT data, to cause a denial of service.
    (CVE-2016-2365)

  - Multiple out-of-bounds read errors exist when handling
    the MXIT protocol. A remote attacker can exploit these,
    via crafted MXIT data, to cause a denial of service.
    (CVE-2016-2366, CVE-2016-2370)

  - An out-of-bounds read error exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    an invalid size for an avatar, to disclose memory
    contents or cause a denial of service. (CVE-2016-2367)

  - Multiple memory corruption issues exist when handling
    the MXIT protocol. A remote attacker can exploit these,
    via crafted MXIT data, to disclose memory contents or
    execute arbitrary code. (CVE-2016-2368)

  - A NULL pointer dereference flaw exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    crafted MXIT packet starting with a NULL byte, to cause
    a denial of service. (CVE-2016-2369)

  - An out-of-bounds write error exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    crafted MXIT data, to corrupt memory, resulting in the
    execution of arbitrary code. (CVE-2016-2371)

  - An out-of-bounds read error exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    an invalid size for a file transfer, to disclose memory
    contents or cause a denial of service. (CVE-2016-2372)

  - An out-of-bounds read error exists when handling the
    MXIT protocol. A remote attacker can exploit this, by
    sending an invalid mood, to cause a denial of service.
    (CVE-2016-2373)

  - An out-of-bounds write error exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    crafted MXIT MultiMX messages, to disclose memory
    contents or execute arbitrary code. (CVE-2016-2374)

  - An out-of-bounds read error exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    crafted MXIT contact information, to disclose memory
    contents. (CVE-2016-2375)

  - A buffer overflow condition exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    a crafted packet having an invalid size, to execute
    arbitrary code. (CVE-2016-2376)

  - An out-of-bounds write error exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    a negative content-length response to an HTTP request,
    to cause a denial of service. (CVE-2016-2377)

  - A buffer overflow condition exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    crafted data using negative length values, to cause a
    denial of service. (CVE-2016-2378)

  - A flaw exists in MXIT due to using weak cryptography
    when encrypting a user password. A man-in-the-middle
    attacker able to access login messages can exploit this
    to impersonate the user. (CVE-2016-2379)

  - An out-of-bounds read error exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    a crafted local message, to disclose memory contents.
    (CVE-2016-2380)

  - A directory traversal flaw exists when handling the
    MXIT protocol. A remote attacker can exploit this, via
    crafted MXIT data using an invalid file name for a
    splash image, to overwrite files. (CVE-2016-4323)

  - An unspecified vulnerability exists due to X.509
    certificates not being properly imported when using
    GnuTLS. No other details are available.");
