Vulnerability Assessment Details

[DSA407] DSA-407-1 ethereal

Vulnerability Assessment Summary
DSA-407-1 ethereal

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
MSISDN string.
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
dereference.
For the stable distribution (woody) this problem has been fixed in
version 0.9.4-1woody6.
For the unstable distribution (sid) this problem has been fixed in
version 0.10.0-1.
We recommend that you upgrade your ethereal and tethereal packages.
