IPSSH (aka the SSH server) in Wind River VxWorks 6.5 through 6.9 allows remote attackers to execute arbitrary code or cause a denial of service (daemon hang) via a crafted public-key authentication request.

An issue was discovered in Wind River VxWorks 7. The memory allocator has a possible integer overflow in calculating a memory block's size to be allocated by calloc(). As a result, the actual memory allocated is smaller than the buffer size specified by the arguments, leading to memory corruption.

The kernel in Amazon Web Services FreeRTOS before 10.4.3 has an integer overflow in streambuffer.c for a stream buffer.

The kernel in Amazon Web Services FreeRTOS before 10.4.3 has an integer overflow in queue.c for queue creation.

IRC5 exposes an ftp server (port 21). Upon attempting to gain access you are challenged with a request of username and password, however you can input whatever you like. As long as the field isn't empty it will be accepted.

An issue was discovered in libmem.c in Micrium uC/OS uC/LIB 1.38.x and 1.39.00. The following memory allocation functions do not check for integer overflow when allocating a pool whose size exceeds the address space: MemPoolCreate, MemDynPoolCreate, and MemDynPoolCreateHW. Because these functions use multiplication to calculate the pool sizes, the operation may cause an integer overflow if the arguments are large enough. The resulting memory pool will be smaller than expected and may be exploited by an attacker.

In MediaTek LinkIt SDK before 4.6.1, there is a possible memory corruption due to an integer overflow during mishandled memory allocation by pvPortCalloc and pvPortRealloc.

An integer overflow vulnerability in the calloc() function of the C runtime library of affected versions of BlackBerry® QNX Software Development Platform (SDP) version(s) 6.5.0SP1 and earlier, QNX OS for Medical 1.1 and earlier, and QNX OS for Safety 1.0.1 and earlier that could allow an attacker to potentially perform a denial of service or execute arbitrary code.

Apache Nuttx Versions prior to 10.1.0 are vulnerable to integer wrap-around in functions malloc, realloc and memalign. This improper memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.

An issue was discovered in Wind River VxWorks before 6.5. There is a possible heap overflow in dhcp client.

An issue was discovered in Wind River VxWorks through 6.8. There is a possible stack overflow in dhcp server.

Wind River VxWorks 6.9 and vx7 has a Buffer Overflow in the TCP component (issue 2 of 4). This is an IPNET security vulnerability: TCP Urgent Pointer state confusion caused by a malformed TCP AO option.

Wind River VxWorks 6.9 and vx7 has a Buffer Overflow in the IPv4 component. There is an IPNET security vulnerability: Stack overflow in the parsing of IPv4 packets’ IP options.

Wind River VxWorks 6.7 though 6.9 and vx7 has a Buffer Overflow in the TCP component (issue 3 of 4). This is an IPNET security vulnerability: TCP Urgent Pointer state confusion during connect() to a remote host.

Wind River VxWorks has a Buffer Overflow in the TCP component (issue 1 of 4). This is a IPNET security vulnerability: TCP Urgent Pointer = 0 that leads to an integer underflow.

ARM mbed product Version 6.3.0 is vulnerable to integer wrap-around in mallocwrapper function, which can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.

TencentOS-tiny version 3.1.0 is vulnerable to integer wrap-around in function 'tosmmheapalloc incorrect calculation of effective memory allocation size. This improper memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.

NXP MCUXpresso SDK versions prior to 2.8.2 are vulnerable to integer overflow in SDKMalloc function, which could allow to access memory locations outside the bounds of a specified array, leading to unexpected behavior such segmentation fault when assigning a particular block of memory from the heap via malloc.

uClibc-ng versions prior to 1.0.37 are vulnerable to integer wrap-around in functions malloc-simple. This improper memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.

RIOT OS version 2020.01.1 is vulnerable to integer wrap-around in its implementation of calloc function, which can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.

NXP MQX Versions 5.1 and prior are vulnerable to integer overflow in memalloc, lwmemalloc and partition functions. This unverified memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.

ARM CMSIS RTOS2 versions prior to 2.1.3 are vulnerable to integer wrap-around inosRtxMemoryAlloc (local malloc equivalent) function, which can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or injected code execution.

eCosCentric eCosPro RTOS Versions 2.0.1 through 4.5.3 are vulnerable to integer wraparound in function calloc (an implementation of malloc). The unverified memory assignment can lead to arbitrary memory allocation, resulting in a heap-based buffer overflow.

Cesanta Software Mongoose-OS v2.17.0 is vulnerable to integer wrap-around in function mmmalloc. This improper memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.

ARM mbed-ualloc memory library version 1.3.0 is vulnerable to integer wrap-around in function mbedkrbs, which can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.

The IPv6 Neighbor Discovery Protocol (NDP) implementation in (1) FreeBSD 6.3 through 7.1, (2) OpenBSD 4.2 and 4.3, (3) NetBSD, (4) Force10 FTOS before E7.7.1.1, (5) Juniper JUNOS, and (6) Wind River VxWorks 5.x through 6.4 does not validate the origin of Neighbor Discovery messages, which allows remote attackers to cause a denial of service (loss of connectivity) or read private network traffic via a spoofed message that modifies the Forward Information Base (FIB).

An issue was discovered in Wind River VxWorks 6.9 and 7. The function tarExtract implements TAR file extraction and thereby also processes files within an archive that have relative or absolute file paths. A developer using the "tarExtract" function may expect that the function will strip leading slashes from absolute paths or stop processing when encountering relative paths that are outside of the extraction path, unless otherwise forced. This could lead to unexpected and undocumented behavior, which in general could result in a directory traversal, and associated unexpected behavior.

Wind River VxWorks 6.6 through 6.9 has a Buffer Overflow in the DHCP client component. There is an IPNET security vulnerability: Heap overflow in DHCP Offer/ACK parsing inside ipdhcpc.
