Description
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 / ethereal0.9.1 – 0.9.1
- ethereal_group / ethereal0.9.2 – 0.9.2
