"The version of Cisco TelePresence TC or TE software running on the
remote host is affected by one or more of the following issues :

  - A denial of service vulnerability exists due to a flaw
    in the SIP implementation, potentially allowing a remote
    attacker to cause a device reload by sending crafted SIP
    packets. (CVE-2014-2162 / CSCud29566)

  - A denial of service vulnerability exists due to a flaw
    in the SIP implementation, potentially allowing a remote
    attacker to cause a device reload by sending crafted SIP
    packets. (CVE-2014-2163 / CSCua64961)

  - A denial of service vulnerability exists due to a flaw
    in the SIP implementation, potentially allowing a remote
    attacker to cause a device reload by sending crafted SIP
    packets. (CVE-2014-2164 / CSCuj94651)

  - A denial of service vulnerability exists due to a flaw
    in the SIP implementation, potentially allowing a remote
    attacker to cause a device reload by sending crafted SIP
    packets. (CVE-2014-2165 / CSCtq72699)

  - A denial of service vulnerability exists due to a flaw
    in the SIP implementation, potentially allowing a remote
    attacker to cause a device reload by sending crafted SIP
    packets. (CVE-2014-2166 / CSCto70562)

  - A denial of service vulnerability exists due to a flaw
    in the SIP implementation, potentially allowing a remote
    attacker to cause a device reload by sending crafted SIP
    packets. (CVE-2014-2167 / CSCua86589)

  - A remote code execution vulnerability exists due to a
    buffer overflow in Cisco TelePresence TC and TE
    software, potentially allowing a remote attacker to
    execute arbitrary code by sending crafted DNS response
    packets. (CVE-2014-2168 / CSCty44804)

  - A remote command execution vulnerability exists due to
    a failure to sanitize user-supplied input to internal
    scripts, potentially allowing an authenticated attacker
    to execute arbitrary commands. (CVE-2014-2169 /
    CSCue60211)

  - A remote command execution vulnerability exists due to
    a failure to sanitize user-supplied input to tshell
    scripts, potentially allowing an authenticated attacker
    to execute arbitrary commands. (CVE-2014-2170 /
    CSCue60202)

  - A remote code execution vulnerability exists that
    potentially allows remote attackers to execute arbitrary
    code via crafted SIP packets. (CVE-2014-2171 /
    CSCud81796)

  - A privilege escalation vulnerability exists due to a
    buffer overflow in Cisco TelePresence TC and TE
    software, potentially allowing local attackers to gain
    privileges. (CVE-2014-2172 / CSCub67693)

  - A privilege escalation vulnerability exists due to
    improperly restricting access to the serial port,
    potentially allowing local attackers to gain privileges
    via unspecified commands. (CVE-2014-2173 / CSCub67692)

  - A denial of service vulnerability exists that
    potentially allows remote attackers to trigger memory
    consumption via crafted H.225 packets.
