egg-compile.scm in CHICKEN 5.x before 5.3.1 allows arbitrary OS command execution during package installation via escape characters in a .egg file.

Buffer overflow in CHICKEN 4.9.0 and 4.9.0.1 may allow remote attackers to execute arbitrary code via the 'select' function.

Multiple buffer overflows in the (1) R5RS char-ready, (2) tcp-accept-ready, and (3) file-select procedures in Chicken through 4.8.0.3 allows attackers to cause a denial of service (crash) by opening a file descriptor with a large integer value. NOTE:...

Chicken before 4.8.0 is susceptible to algorithmic complexity attacks related to hash table collisions.

A casting error in Chicken before 4.8.0 on 64-bit platform caused the random number generator to return a constant value. NOTE: the vendor states "This function wasn't used for security purposes (and is advertised as being unsuitable)."

Chicken before 4.8.0 does not properly handle NUL bytes in certain strings, which allows an attacker to conduct "poisoned NUL byte attack."

Buffer overflow in the thread scheduler in Chicken before 4.8.0.1 allows attackers to cause a denial of service (crash) by opening a file descriptor with a large integer value.

OS command injection vulnerability in the "qs" procedure from the "utils" module in Chicken before 4.9.0.

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...

An incorrect "pair?" check in the Scheme "length" procedure results in an unsafe pointer dereference in all CHICKEN Scheme versions prior to 4.13, which allows an attacker to cause a denial of service by passing an improper list to an application tha...
