CVE-2002-0353: Ethereal Group Ethereal

Medium severity, CVSS 5.0. EPSS: 2.7% chance of exploitation in the next 30 days.

The ASN.1 parser in Ethereal 0.9.2 and earlier allows remote attackers to cause a denial of service (crash) via a certain malformed packet, which causes Ethereal to allocate memory incorrectly, possibly due to zero-length fields.

Affected products

• Ethereal Group Ethereal: version 0.9.1 only; version 0.9.2 only
