Vulnerability Assessment Details
Detailed Explanation for this Vulnerability Assessment
Several vulnerabilities were discovered upstream in ethereal, a
network traffic analyzer. The Common Vulnerabilities and Exposures
project identifies the following problems:
A buffer overflow permits 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 permits remote attackers to cause a
denial of service (crash) and possibly execute arbitrary code via
the SOCKS dissector.
The SMB dissector permits 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 permits 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
For the unstable distribution (sid) this problem has been fixed in
We recommend that you upgrade your ethereal and tethereal packages.
