CVE-2006-4024: Festalon

High severity, CVSS 7.5. EPSS: 5.1% chance of exploitation in the next 30 days.

The FESTAHES_Load function in pce/hes.c in Festalon 0.5.0 through 0.5.5 allows user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code via a negative LoadAddr value in a HES file, which is used as an offset in a memcpy operation and leads to a buffer underflow.

Affected products

• Festalon Festalon: up to and including 0.5.5; version 0.5.0 only
