[DSA407] DSA-407-1 ethereal Vulnerability Scan
Vulnerability Scan Summary
Detailed Explanation for this Vulnerability Test
Several vulnerabilities were discovered upstream in ethereal, a
network traffic analyzer. The Common Vulnerabilities and Exposures
project identifies the following problems:
A buffer overflow allows remote attackers to cause a denial of
service and possibly execute arbitrary code via a malformed GTP
Via certain malformed ISAKMP or MEGACO packets remote attackers are
able to cause a denial of service (crash).
A heap-based buffer overflow allows remote attackers to cause a
denial of service (crash) and possibly execute arbitrary code via
the SOCKS dissector.
The SMB dissector allows remote attackers to cause a denial of
service via a malformed SMB packet that triggers a segmentation
fault during processing of selected packets.
The Q.931 dissector allows remote attackers to cause a denial of
service (crash) via a malformed Q.931, which triggers a null
For the stable distribution (woody) this problem has been fixed in
