Buffer Overflow in hoeldb.c: How sprintf() Threatened a Racing Sim's Database Layer
A critical buffer overflow vulnerability was discovered in `src/simmonitor/db/hoeldb.c`, where fixed-size heap buffers (150 and 250 bytes) were allocated with `malloc()` and then written to using `sprintf()` without any bounds checking. The fix replaces these unsafe patterns with `asprintf()` for dynamic allocation and `calloc()` for row data buffers, eliminating both the overflow risk and a related uninitialized memory hazard.
Local File Inclusion in Crawl4AI Docker API via file:// URL Injection
CVE-2026-26217 is a critical Local File Inclusion (LFI) vulnerability in Crawl4AI versions prior to 0.8.0, where the Docker API fails to restrict `file://` URL schemes, allowing attackers to read arbitrary files from the host filesystem. The fix upgrades `crawl4ai` from `0.7.6` to `0.8.0` in `pyproject.toml` and `uv.lock`, closing a direct path to sensitive file exfiltration in any containerized deployment using this library.
Heap Buffer Overflow in Audio Ring Buffer: How a Missing Bounds Check Could Crash Your App
A critical heap buffer overflow vulnerability was discovered in `audio_backend.c`, where the audio ring buffer's `memcpy` operations lacked bounds validation before writing PCM data. Without checking that incoming data sizes fell within the allocated buffer's capacity, a maliciously crafted audio file could corrupt adjacent heap memory, potentially enabling arbitrary code execution. The fix adds a concise pre-flight validation guard that rejects out-of-range write requests before any memory oper
Critical Memory Safety Bug: Free of Uninitialized Memory in Rust Telemetry (CVE-2021-29937)
CVE-2021-29937 is a critical memory safety vulnerability in the Rust `telemetry` crate (versions prior to 0.1.3) that allows freeing uninitialized memory, leading to undefined behavior, potential crashes, and possible code execution. The fix involves upgrading the crate from version 0.1.0 to 0.1.3, which patches the unsafe memory handling at the root cause. Despite Rust's reputation for memory safety, this vulnerability demonstrates that `unsafe` code blocks can still introduce serious bugs that
Critical Heap Buffer Overflow in SSDP Control Point: How Unbounded String Operations Put Networks at Risk
A critical heap buffer overflow vulnerability was discovered and patched in the SSDP control point implementation (`ssdp_ctrlpt.c`), where multiple unbounded `strcpy` and `strcat` operations constructed HTTP request buffers without any length validation. Network-received SSDP response fields — including service type strings and location URLs — could be crafted by an attacker to exceed buffer boundaries, potentially enabling arbitrary code execution or denial of service. The fix replaces the unsa
Heap Buffer Overflow in OPDS Parser: How a Misplaced Variable Nearly Opened the Door to Remote Code Execution
A critical heap buffer overflow vulnerability was discovered in `lib/OpdsParser/OpdsParser.cpp`, where the buffer allocation size was calculated *after* a fixed chunk size was used to allocate memory, meaning the actual bytes read could exceed the allocated buffer. On embedded devices parsing untrusted OPDS catalog data from the network, this flaw could allow a remote attacker to corrupt heap memory and potentially achieve arbitrary code execution. The fix was elegantly simple: move the `toRead`
