CVE-2014-6310

CWE-120
 
 
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-2012-6123

CWE-20
 
 
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-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.

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.

CVE-2015-4556

 
 
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

 
 
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

 
 
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-2016-6830

 
 
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).

 
2015-08-28
 
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 attackers to have unspecified impact via a positive START argument to the "substring-index[-ci] procedures."

 
2014-09-29
 
CVE-2013-1874

CWE-Other
 
 
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.
