CriticalMetricsAV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions
CHICKEN Scheme versions prior to 4.13
Description
The issue arises from an incorrect "pair?" check in the Scheme "length" procedure, leading to an unsafe pointer dereference. This allows an attacker to cause a denial of service by passing an improper list to an application that calls "length" on it.
Recommendations
For versions prior to 4.13, update to version 4.13 or later to resolve the issue.
