Unspecified vulnerability in the sFlow dissector in Wireshark 1.2.0 allows remote attackers to cause a denial of service (CPU and memory consumption) via unspecified vectors.

Rebased to 1.2.x, fixing several security flaws, see the security advisory for details:
http://www.wireshark.org/security/wnpa-sec-2009-04.html

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Update to Wireshark 1.2.2 fixing multiple security issues:
http://www.wireshark.org/docs/relnotes/wireshark-1.2.2.html http://www.wireshark.org/security/wnpa-sec-2009-06.html * The OpcUa dissector could use excessive CPU and memory. (Bug 3986) Versions affected: 0.99.6 to 1.0.8, 1.2.0 to 1.2.1 * The GSM A RR dissector could crash. (Bug 3893) Versions affected: 1.2.0 to 1.2.1 * The TLS dissector could crash on some platforms. (Bug 4008) Versions affected:
1.2.0 to 1.2.1 http://www.wireshark.org/docs/relnotes/wireshark-1.2.1.html http://www.wireshark.org/security/wnpa-sec-2009-04.html * The AFS dissector could crash. (Bug 3564) Versions affected: 0.9.2 to 1.2.0

  - The Infiniband dissector could crash on some platforms.
    Versions affected: 1.0.6 to 1.2.0 * The IPMI dissector     could overrun a buffer. (Bug 3559) Versions affected:
    1.2.0 * The Bluetooth L2CAP dissector could crash. (Bug     3572) Versions affected: 1.2.0 * The RADIUS dissector     could crash. (Bug 3578) Versions affected: 1.2.0 * The     MIOP dissector could crash. (Bug 3652) Versions     affected: 1.2.0 * The sFlow dissector could use     excessive CPU and memory. (Bug 3570) Versions affected:
    1.2.0 (Issues from wnpa-sec-2009-04 does not affect     users of Wireshark 1.2.1 packages from updates-testing.)

The remote host is affected by the vulnerability described in GLSA-200909-16 (Wireshark: Denial of Service)

    Multiple vulnerabilities were discovered in Wireshark:
    A     buffer overflow in the IPMI dissector related to an array index error     (CVE-2009-2559).
    Multiple unspecified vulnerabilities in the     Bluetooth L2CAP, RADIUS, and MIOP dissectors (CVE-2009-2560).
    An unspecified vulnerability in the sFlow dissector     (CVE-2009-2561).
    An unspecified vulnerability in the AFS     dissector (CVE-2009-2562).
    An unspecified vulnerability in the     Infiniband dissector when running on unspecified platforms     (CVE-2009-2563).
  Impact :

    A remote attacker could exploit these vulnerabilities by sending     specially crafted packets on a network being monitored by Wireshark or     by enticing a user to read a malformed packet trace file to cause a     Denial of Service.
  Workaround :

    There is no known workaround at this time.

The installed version of Wireshark or Ethereal is affected by multiple issues :

  - The IPMI dissector could overrun a buffer. (Bug 3559)

  - The AFS dissector could crash. (Bug 3564)

  - The Infiniband dissector could crash on some platforms.

  - The Bluetooth L2CAP dissector could crash. (Bug 3572)

  - The RADIUS dissector could crash. (Bug 3578)

  - The MIOP dissector could crash. (Bug 3652)

  - The sFlow dissector could use excessive CPU and memory.
    (Bug 3570)

These vulnerabilities could result in a denial of service, or possibly arbitrary code execution.  A remote attacker could exploit these issues by tricking a user into opening a maliciously crafted capture file.  Additionally, if Wireshark is running in promiscuous mode, one of these issues could be exploited remotely (from the same network segment).
