Use After Free vulnerability in No-Chicken Echo-Mate.This issue affects Echo-Mate: before V250329.

Use After Free vulnerability in No-Chicken Echo-Mate (‎SDK/rv1106-sdk/sysdrv/source/kernel/mm modules). This vulnerability is associated with program files rmap.C‎. This issue affects Echo-Mate: before V250329.

Improper Handling of Values vulnerability in No-Chicken Echo-Mate (SDK/rv1106-sdk/sysdrv/source/kernel/include/net/netfilter modules). This vulnerability is associated with program files nf_tables.H‎, nft_byteorder.C‎, nft_meta.C‎. This issue affects Echo-Mate: before V250329.

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.

Buffer overflow in CHICKEN 4.9.0 and 4.9.0.1 may allow remote attackers to execute arbitrary code via the 'select' function.

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.

Chicken before 4.8.0 is susceptible to algorithmic complexity attacks related to hash table collisions.

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)."

Chicken before 4.8.0 does not properly handle NUL bytes in certain strings, which allows an attacker to conduct "poisoned NUL byte attack."

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.

OS command injection vulnerability in the "qs" procedure from the "utils" module in Chicken before 4.9.0.

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.

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.

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).

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.

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…

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…

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."

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.

The Ninja Chicken Ooga Booga (aka mominis.Generic_Android.Ninja_Chicken_Ooga_Booga) application 1.4.2 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

The Ninja Chicken Adventure Island (aka mominis.Generic_Android.Ninja_Chicken_Adventure_Island) application 1.1.1 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

The Ninja Chicken (aka mominis.Generic_Android.Ninja_Chicken) application 1.7.6 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

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.

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.

Chicken of the VNC (cotv) 2.0 allows remote attackers to cause a denial of service (application crash) via a large computer-name size value in a ServerInit packet, which triggers a failed malloc and a resulting NULL dereference.
