Heap-based Buffer Overflow

A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

A vulnerability has been identified in the libarchive library. This flaw can lead to a heap buffer over-read due to the size of a filter block potentially exceeding the Lempel-Ziv-Storer-Schieber (LZSS) window. This means the library may attempt to read beyond the allocated memory buffer, which can result in unpredictable program behavior, crashes (denial of service), or the disclosure of sensitive information from adjacent memory regions.Show less

WOLFBOX Level 2 EV Charger tuya_svc_devos_activate_result_parse Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of WOLFBOX Level 2 EV Charger. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the secKey, localKey, stdTimeZone and devId parameters. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-26294.Show less

NeKernal is a free and open-source operating system stack. Version 0.0.2 has a 1-byte heap overflow in `rt_copy_memory`, which unconditionally wrote a null terminator at `dst[len]`. When `len` equals the size of the destination buffer (256 bytes), that extra `'\0'` write overruns the buffer by one byte. To avoid breaking existing callers or changing the public API, the patch in commit fb7b7f658327f659c6a6da1af151cb389c2ca4ee takes a minimal approach: it simply removes the overflow-causing line without adding bounds checks or altering the function signature.Show less
