SecurityTracker Alert ID:  1016736
SecurityTracker URL:  http://securitytracker.com/id/1016736
CVE Reference:   CVE-2006-4330, CVE-2006-4331, CVE-2006-4332, CVE-2006-4333   (Links to External Site)
Updated:  Sep 12 2006
Original Entry Date:  Aug 23 2006
Impact:   Denial of service via network, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 0.7.9 - 0.99.2
Description:   A vulnerability was reported in Wireshark (Ethereal). A remote user can execute arbitrary code on the target system. A remote user can cause denial of service conditions.

If Wireshark was compiled with IPSec ESP decryption support, a remote user can send specially crafted data to trigger an off-by-one error in the IPSec ESP preference parser. Only version 0.99.2 is affected.

A remote user can send specially crafted data to cause the SCSI dissector to crash. Only version 0.99.2 is affected.

A remote user can send specially crafted DHCP data to trigger a flaw in Glib on Windows-based systems and cause the DHCP dissector to crash. Other dissectors may also be affected. Versions 0.10.13 - 0.99.2 are vulnerable.

If the SSCOP dissector has a port range configured (which is not the default configuration) and the SSCOP payload protocol is Q.2931, a remote user can send a specially crafted packet to cause the Q.2931 dissector to consume all available memory. Versions 0.7.9 - 0.99.2 are affected.

These vulnerabilities can also be triggered by a specially crafted packet trace file.

Impact:   A remote user can execute arbitrary code on the target system.

A remote user can cause denial of service conditions.

Solution:   The vendor has issued a fixed version (0.99.3).
