3,698 CVEs • Abstraction: Variant • Likelihood of Exploit: High

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().

CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. In versions 1.3.3 and prior, an unsigned integer underflow in the `Crypto_TC_ProcessSecurity` function of CryptoLib leads to a heap buffer overflow. The vulnerability is triggered when the `fl` (frame length) field in a Telecommand (TC) packet is set to 0. This underflow causes the frame length to be interpreted as 65535, resulting in out-of-bounds memory access. This critical vulnerability can be exploited to cause a denial of service (DoS) or potentially achieve remote code execution. Users of CryptoLib are advised to apply the recommended patch or avoid processing untrusted TC packets until a fix is available.Show less

CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. A critical heap buffer overflow vulnerability was identified in the `Crypto_AOS_ProcessSecurity` function of CryptoLib versions 1.3.3 and prior. This vulnerability allows an attacker to trigger a Denial of Service (DoS) or potentially execute arbitrary code (RCE) by providing a maliciously crafted AOS frame with an insufficient length. The vulnerability lies in the function `Crypto_AOS_ProcessSecurity`, specifically during the processing of the Frame Error Control Field (FECF). The affected code attempts to read from the `p_ingest` buffer at indices `current_managed_parameters_struct.max_frame_size - 2` and `current_managed_parameters_struct.max_frame_size - 1` without verifying if `len_ingest` is sufficiently large. This leads to a heap buffer overflow when `len_ingest` is smaller than `max_frame_size`. As of time of publication, no known patched versions exist.Show less

Ashlar-Vellum Cobalt VC6 File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of VC6 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25252.Show less
