| CVE | Sev | Risk | CVSS | EPSS | KEV | Published | Description |
|---|---|---|---|---|---|---|---|
| CVE-2016-6830 | Cri | 0.64 | 9.8 | 0.00 | 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 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-2017-6949 | Hig | 0.53 | 8.1 | 0.00 | 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 have been a segfault or buffer overflow. | |
| CVE-2017-11343 | Hig | 0.49 | 7.5 | 0.00 | 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-2017-9334 | Hig | 0.49 | 7.5 | 0.00 | 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 | 0.01 | 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 including 4.11 (it will be fixed in 4.12 and 5.0, which are not yet released). | |
| CVE-2014-9651 | 0.00 | — | 0.00 | 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 | — | 0.03 | 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" value in the NUM argument. | ||
| CVE-2013-4385 | 0.00 | — | 0.03 | Oct 9, 2013 | 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. |
