Call-Cc Chicken vulnerabilities

CVE-2013-2024 [HIGH] CWE-78 CVE-2013-2024: OS command injection vulnerability in the "qs" procedure from the "utils" module in Chicken before 4 OS command injection vulnerability in the "qs" procedure from the "utils" module in Chicken before 4.9.0.

CVE-2022-45145 [CRITICAL] CWE-78 CVE-2022-45145: egg-compile.scm in CHICKEN 5.x before 5.3.1 allows arbitrary OS command execution during package ins 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.

CVE-2016-6830 [CRITICAL] CWE-119 CVE-2016-6830: The "process-execute" and "process-spawn" procedures in CHICKEN Scheme used fixed-size buffers for h The "process-execute" and "process-spawn" procedures in CHICKEN Scheme used fixed-size buffers for holding the arguments and environment variables to use in its execve() call. This would allow user-supplied argument/environment variable lists to trigger a buffer overrun. This affects all releases of CHICKEN up to and including 4.11 (it will be fixed

CVE-2014-6310 [CRITICAL] CWE-120 CVE-2014-6310: Buffer overflow in CHICKEN 4.9.0 and 4.9.0.1 may allow remote attackers to execute arbitrary code vi Buffer overflow in CHICKEN 4.9.0 and 4.9.0.1 may allow remote attackers to execute arbitrary code via the 'select' function.

CVE-2017-6949 [HIGH] CWE-119 CVE-2017-6949: An issue was discovered in CHICKEN Scheme through 4.12.0. When using a nonstandard CHICKEN-specific 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-2012-6125 [CRITICAL] CWE-20 CVE-2012-6125: Chicken before 4.8.0 is susceptible to algorithmic complexity attacks related to hash table collisio Chicken before 4.8.0 is susceptible to algorithmic complexity attacks related to hash table collisions.

CVE-2013-2075 [HIGH] CVE-2013-2075: Multiple buffer overflows in the (1) R5RS char-ready, (2) tcp-accept-ready, and (3) file-select proc 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-2014-3776 [HIGH] CWE-119 CVE-2014-3776: Buffer overflow in the "read-u8vector!" procedure in the srfi-4 unit in CHICKEN stable 4.8.0.7 and d Buffer overflow in the "read-u8vector!" procedure in the srfi-4 unit in CHICKEN stable 4.8.0.7 and development snapshots before 4.9.1 allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly execute arbitrary code via a "#f" value in the NUM argument.

CVE-2017-11343 [HIGH] CVE-2017-11343: Due to an incomplete fix for CVE-2012-6125, all versions of CHICKEN Scheme up to and including 4.12. 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-2013-4385 [HIGH] CWE-119 CVE-2013-4385: Buffer overflow in the "read-string!" procedure in the "extras" unit in CHICKEN stable before 4.8.0. Buffer overflow in the "read-string!" procedure in the "extras" unit in CHICKEN stable before 4.8.0.5 and development snapshots before 4.8.3 allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly execute arbitrary code via a "#f" value in the NUM argument.

CVE-2016-6831 [HIGH] CWE-400 CVE-2016-6831: The "process-execute" and "process-spawn" procedures did not free memory correctly when the execve() 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)

CVE-2015-4556 [HIGH] CWE-20 CVE-2015-4556: The string-translate* procedure in the data-structures unit in CHICKEN before 4.10.0 allows remote a 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-2014-9651 [HIGH] CWE-119 CVE-2014-9651: Buffer overflow in CHICKEN 4.9.0.x before 4.9.0.2, 4.9.x before 4.9.1, and before 5.0 allows attacke Buffer overflow in CHICKEN 4.9.0.x before 4.9.0.2, 4.9.x before 4.9.1, and before 5.0 allows attackers to have unspecified impact via a positive START argument to the "substring-index[-ci] procedures."

CVE-2017-9334 [HIGH] CWE-20 CVE-2017-9334: An incorrect "pair?" check in the Scheme "length" procedure results in an unsafe pointer dereference 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-2012-6122 [HIGH] CWE-120 CVE-2012-6122: Buffer overflow in the thread scheduler in Chicken before 4.8.0.1 allows attackers to cause a denial 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-2012-6123 [MEDIUM] CWE-20 CVE-2012-6123: Chicken before 4.8.0 does not properly handle NUL bytes in certain strings, which allows an attacker Chicken before 4.8.0 does not properly handle NUL bytes in certain strings, which allows an attacker to conduct "poisoned NUL byte attack."

CVE-2012-6124 [MEDIUM] CWE-338 CVE-2012-6124: A casting error in Chicken before 4.8.0 on 64-bit platform caused the random number generator to ret 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)."

CVE-2013-1874 [MEDIUM] CVE-2013-1874: Untrusted search path vulnerability in csi in Chicken before 4.8.2 allows local users to execute arb Untrusted search path vulnerability in csi in Chicken before 4.8.2 allows local users to execute arbitrary code via a Trojan horse .csirc in the current working directory.
