A flaw was found in newlib in versions prior to 4.0.0. Improper overflow validation in the memory allocation functions mEMALIGn, pvALLOc, nanomemalign, nanovalloc, nanopvalloc could case an integer overflow, leading to an allocation of a small buffer and then to a heap-based buffer overflow.
A vulnerability has been identified in APOGEE PXC Compact (BACnet) (All versions < V3.5.5), APOGEE PXC Compact (P2 Ethernet) (All versions < V2.8.20), APOGEE PXC Modular (BACnet) (All versions < V3.5.5), APOGEE PXC Modular (P2 Ethernet) (All versions < V2.8.20), Nucleus NET (All versions < V5.2), Nucleus ReadyStart V3 (All versions < V2012.12), Nucleus Source Code (All versions), PLUSCONTROL 1st Gen (All versions), TALON TC Compact (BACnet) (All versions < V3.5.5), TALON TC Modular (BACnet) (All versions < V3.5.5). Initial Sequence Numbers (ISNs) for TCP connections are derived from an insufficiently random source. As a result, the ISN of current and future TCP connections could be predictable. An attacker could hijack existing sessions or spoof future ones.
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.
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.
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.
Micrium OS Versions 5.10.1 and prior are vulnerable to integer wrap-around in functions MemDynPoolCreate, MemDynPoolCreateHW and MemPoolCreate. This unverified memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as very small blocks of memory being allocated instead of very large ones.
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.
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 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.
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.
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.
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.
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.
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.
An issue was discovered in Ethernut Nut/OS 5.1. The code that generates Initial Sequence Numbers (ISNs) for TCP connections derives the ISN from an insufficiently random source. As a result, an attacker may be able to determine the ISN of current and future TCP connections and either hijack existing ones or spoof future ones. While the ISN generator seems to adhere to RFC 793 (where a global 32-bit counter is incremented roughly every 4 microseconds), proper ISN generation should aim to follow at least the specifications outlined in RFC 6528.
In Silicon Labs uC/TCP-IP 3.6.0, TCP ISNs are improperly random.
In Oryx CycloneTCP 1.9.6, TCP ISNs are improperly random.
In Microchip MPLAB Net 3.6.1, TCP ISNs are improperly random.
In FNET 4.6.3, TCP ISNs are improperly random.
In Contiki 4.5, TCP ISNs are improperly random.
In PicoTCP 1.7.0, TCP ISNs are improperly random.
Integer Overflow in memory allocating functions. Zephyr versions >= 1.14.2, >= 2.4.0 contain Integer Overflow or Wraparound (CWE-190). For more information, see https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-94vp-8gc2-rm45
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.
In Wind River VxWorks, memory allocator has a possible overflow in calculating the 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.
In SIMATIC MV400 family versions prior to v7.0.6, the ISN generator is initialized with a constant value and has constant increments. An attacker could predict and hijack TCP sessions.
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.
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.
Texas Instruments TI-RTOS, when configured to use HeapMem heap(default), malloc returns a valid pointer to a small buffer on extremely large values, which can trigger an integer overflow vulnerability in 'HeapMemallocUnprotected' and result in code execution.
Texas Instruments devices running FREERTOS, malloc returns a valid pointer to a small buffer on extremely large values, which can trigger an integer overflow vulnerability in 'malloc' for FreeRTOS, resulting in code execution.
