Details

Description:
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
crash.
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
Impact:
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.
Resolution:
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.
