| CVE-2016-6830 | Cri | 0.64 | 9.8 | 0.02 | Jan 10, 2017 | 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… | ||
| CVE-2017-6949 | Hig | 0.53 | 8.1 | 0.01 | Mar 16, 2017 | 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… | ||
| CVE-2017-11343 | Hig | 0.49 | 7.5 | 0.01 | Jul 17, 2017 | 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-2015-8235 | Hig | 0.49 | 7.5 | 0.03 | Jun 7, 2017 | Directory traversal vulnerability in Spiffy before 5.4. | ||
| CVE-2017-9334 | Hig | 0.49 | 7.5 | 0.02 | Jun 1, 2017 | 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-2015-4556 | Hig | 0.49 | 7.5 | 0.02 | Mar 29, 2017 | 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-2016-6831 | Hig | 0.49 | 7.5 | 0.02 | Jan 10, 2017 | 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… | ||
| CVE-2016-6287 | Hig | 0.49 | 7.5 | 0.01 | Jan 10, 2017 | The "http-client" egg always used a HTTP_PROXY environment variable to determine whether HTTP traffic should be routed via a proxy, even when running as a CGI process. Under several web servers this would mean a user-supplied "Proxy" header could allow an attacker to direct all… | ||
| CVE-2016-6286 | Hig | 0.49 | 7.5 | 0.01 | Jan 10, 2017 | The "spiffy-cgi-handlers" egg would convert a nonexistent "Proxy" header to the HTTP_PROXY environment variable, which would allow attackers to direct CGI programs which use this environment variable to use an attacker-specified HTTP proxy server (also known as a "httpoxy"… | ||
| CVE-2014-6310 | 0.01 | — | 0.05 | Nov 22, 2019 | 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-2022-45145 | 0.00 | — | 0.01 | Dec 10, 2022 | 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-2012-6125 | 0.00 | — | 0.02 | Oct 31, 2019 | Chicken before 4.8.0 is susceptible to algorithmic complexity attacks related to hash table collisions. | |||
| CVE-2012-6124 | 0.00 | — | 0.01 | Oct 31, 2019 | 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-2012-6123 | 0.00 | — | 0.01 | Oct 31, 2019 | 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-2012-6122 | 0.00 | — | 0.02 | Oct 31, 2019 | 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-2013-2075 | 0.00 | — | 0.02 | Oct 31, 2019 | 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… | |||
| CVE-2014-9651 | 0.00 | — | 0.01 | Aug 28, 2015 | 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-2013-1874 | 0.00 | — | 0.00 | Sep 29, 2014 | 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. | |||
| CVE-2014-3776 | 0.00 | — | 0.04 | May 20, 2014 | 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"… | |||
