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.
