Due to an incomplete fix for CVE-2012-6125, all versions of CHICKEN Scheme up to and including 4.12.0 are vulnerable to an algorithmic complexity attack. An attacker can provide crafted input which, when inserted into the symbol table, will result in O(n) lookup time.

Security readout for executives and security teams

CHICKEN Scheme versions up to and including 4.12.0 can be slowed by specially crafted input. If a reachable application feeds attacker-controlled data into CHICKEN's symbol table, this may cause excessive CPU work and service degradation. Exposure is likely limited to applications, services, or tooling using CHICKEN Scheme up to 4.12.0 where untrusted input can create or insert symbols. Prioritize if CHICKEN Scheme is used in internet-facing or multi-tenant services. Otherwise, handle through normal dependency remediation and inventory cleanup. Mitigation focus: Inventory CHICKEN Scheme usage and identify versions up to and including 4.12.0.; Check CHICKEN project guidance for a fixed release or recommended upgrade path.; Reduce or validate untrusted input paths that create symbols..
