2019-10-31 CVE-2013-2024 OS command injection vulnerability in the "qs" procedure from the "utils" module in Chicken before 4.9.0. Chicken, Debian_linux N/A
2019-10-31 CVE-2012-6123 Chicken before 4.8.0 does not properly handle NUL bytes in certain strings, which allows an attacker to conduct "poisoned NUL byte attack." Chicken, Debian_linux N/A
2019-10-31 CVE-2013-2075 Multiple buffer overflows in the (1) R5RS char-ready, (2) tcp-accept-ready, and (3) file-select procedures in Chicken through allows attackers to cause a denial of service (crash) by opening a file descriptor with a large integer value. NOTE: this issue exists because of an incomplete fix for CVE-2012-6122. Chicken N/A
2019-10-31 CVE-2012-6124 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 N/A
2019-10-31 CVE-2012-6125 Chicken before 4.8.0 is susceptible to algorithmic complexity attacks related to hash table collisions. Chicken N/A
2019-10-31 CVE-2012-6122 Buffer overflow in the thread scheduler in Chicken before allows attackers to cause a denial of service (crash) by opening a file descriptor with a large integer value. Chicken N/A
2017-06-01 CVE-2017-9334 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 that calls "length" on it. Chicken 7.5
2017-03-16 CVE-2017-6949 An issue was discovered in CHICKEN Scheme through 4.12.0. When using a nonstandard CHICKEN-specific extension to allocate an SRFI-4 vector in unmanaged memory, the vector size would be used in unsanitised form as an argument to malloc(). With an unexpected size, the impact may have been a segfault or buffer overflow. Chicken 8.1
2017-07-17 CVE-2017-11343 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. Chicken 7.5
2017-01-10 CVE-2016-6831 The "process-execute" and "process-spawn" procedures did not free memory correctly when the execve() call failed, resulting in a memory leak. This could be abused by an attacker to cause resource exhaustion or a denial of service. This affects all releases of CHICKEN up to and including 4.11 (it will be fixed in 4.12 and 5.0, which are not yet released). Chicken 7.5
