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.

CVE-2017-11343 chicken: Predictable symbol table due to using default libc seed in PRNG
A flaw was found in CHICKEN Scheme symbol table randomization algorithm. The code that sets up the initial symbol table is run _before_ initializing the PRNG, which means the randomization factor uses the initial libc seed state. On most libc implementations this means the symbol table randomization factor is a constant value which does not differ between runs.
