Vulnerability Assessment Details
Check for the version of the ethereal packages
Detailed Explanation for this Vulnerability Assessment
Updated Ethereal packages that fix a number of exploitable security issues
are now available.
Ethereal is a program for monitoring network traffic.
A number of security issues affect Ethereal. By exploiting these issues,
it may be possible to make Ethereal crash or run arbitrary code by
injecting a purposefully-malformed packet onto the wire or by convincing
someone to read a malformed packet trace file.
A buffer overflow in Ethereal 0.9.15 and earlier permits remote attackers
to cause a denial of service and possibly execute arbitrary code via a
malformed GTP MSISDN string. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2003-0925 to
Ethereal 0.9.15 and earlier permits remote attackers to cause a denial of
service (crash) via certain malformed ISAKMP or MEGACO packets. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CVE-2003-0926 to this issue.
A heap-based buffer overflow in Ethereal 0.9.15 and earlier permits
remote attackers to cause a denial of service (crash) and possibly
execute arbitrary code via the SOCKS dissector. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0927
to this issue.
Users of Ethereal should update to these erratum packages containing
Ethereal version 0.9.16, which is not vulnerable to these issues.
