Ethereal Security Advisory 16 (PacketStormID:F35461)

advisory,denial of service,vulnerability

Ethereal Security Advisory Enpa-sa-00016 - Multiple vulnerabilities in Ethereal versions 0.9.0 to 0.10.7 have been discovered that all result in denial of service outcomes.

*Name:* Multiple problems in Ethereal versions 0.9.0 to 0.10.7

*Docid:* enpa-sa-00016

*Date:* December 15, 2004

*Versions affected:* 0.9.0 up to and including 0.10.7

*Severity:* *High*



Issues have been discovered in the following protocol dissectors:

    * Matthew Bing discovered a bug in DICOM dissection that could make
      Ethereal crash.
      Versions affected: 0.10.4 - 0.10.7
      CVE: CAN-2004-1139

    * An invalid RTP timestamp could make Ethereal hang and create a
      large temporary file, possibly filling available disk space.
      Versions affected: 0.9.16 - 0.10.7
      CVE: CAN-2004-1140

    * The HTTP dissector could access previously-freed memory, causing a
      Versions affected: 0.10.1 - 0.10.7
      CVE: CAN-2004-1141

    * Brian Caswell discovered that an improperly formatted SMB packet
      could make Ethereal hang, maximizing CPU utilization.
      Versions affected: 0.9.0 - 0.10.7
      CVE: CAN-2004-1142


It may be possible to make Ethereal crash or run arbitrary code by
injecting a purposefully malformed packet onto the wire or by convincing
someone to read a malformed packet trace file.


Upgrade to 0.10.8.

If you are running a version prior to 0.10.8 and you cannot upgrade, you
can disable the HTTP, DICOM, and SMB protocol dissectors by selecting
/Analyze->Enabled Protocols.../ and deselecting them from the list.
However, it is strongly recommended that you upgrade to 0.10.8.

Please send support questions about Ethereal to the
ethereal-users[AT] <mailto:ethereal-users[AT]>
mailing list.
