CVE-2013-2024 2 Call-cc, Debian 2 Chicken, Debian Linux 2020-08-18 9.0 HIGH 8.8 HIGH
OS command injection vulnerability in the "qs" procedure from the "utils" module in Chicken before 4.9.0.
CVE-2017-9334 1 Call-cc 1 Chicken 2020-08-05 5.0 MEDIUM 7.5 HIGH
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.
CVE-2013-2075 1 Call-cc 1 Chicken 2019-11-06 7.5 HIGH 8.8 HIGH
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: this issue exists because of an incomplete fix for CVE-2012-6122.
CVE-2012-6122 1 Call-cc 1 Chicken 2019-11-05 5.0 MEDIUM 7.5 HIGH
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.
CVE-2017-11343 1 Call-cc 1 Chicken 2017-07-26 5.0 MEDIUM 7.5 HIGH
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-2015-4556 1 Call-cc 1 Chicken 2017-07-01 5.0 MEDIUM 7.5 HIGH
The string-translate* procedure in the data-structures unit in CHICKEN before 4.10.0 allows remote attackers to cause a denial of service (crash).
CVE-2017-6949 1 Call-cc 1 Chicken 2017-04-05 6.8 MEDIUM 8.1 HIGH
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.
CVE-2016-6831 1 Call-cc 1 Chicken 2017-01-11 5.0 MEDIUM 7.5 HIGH
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).
