CVE-2004-0176: Multiple buffer overflows in Ethereal 0.8.13 to 0.10.2 allow remote attackers to cause a denial of service...

Security readout for executives and security teams

CVE-2004-0176 affects old Ethereal network analyzer versions 0.8.13 through 0.10.2. A specially crafted network input handled by several protocol dissectors could crash the tool and may allow arbitrary code execution. Business risk is mainly in legacy systems still using Ethereal to inspect untrusted traffic or capture files. Exposure is likely limited to legacy hosts with Ethereal 0.8.13 to 0.10.2 installed, especially systems analyzing untrusted live traffic or packet captures. Modern environments are affected only if this obsolete package remains present. Treat as high priority only where legacy Ethereal is still present. The technology is old, but the impact includes possible code execution, so any remaining installations should be found and removed or fixed promptly. Mitigation focus: Inventory systems for Ethereal 0.8.13 through 0.10.2.; Replace affected Ethereal packages with vendor-fixed or supported versions.; Consult Debian, Gentoo, Red Hat, and CERT guidance for platform-specific remediation..
