#buffer_overflow

This blog explains why vulnerability scoring matters, how CVSS works, and what’s new in version 4.0.

Cisco Talos’ Vulnerability Discovery & Research team recently disclosed five vulnerabilities in Dell ControlVault 3 firmware and its associated Windows software, four vulnerabilities in Entr'ouvert Lasso, and one vulnerability in GL.iNet Slate AX. The vulnerabilities mentioned in this blog post have been patched by their respective

A heap-buffer-overflow vulnerability exists in the Rust wrapper for libnftnl, triggered via the nftnl::Batch::with_page_size constructor. When a small or malformed page size is provided, the underlying C code allocates an insufficient buffer, leading to out-of-bounds writes during batch initialization. The flaw was fixed in commit 94a286f by adding an overflow check: ```Rust batch_page_size .checked_add(crate::nft_nlmsg_maxsize()) .expect("batch_page_size is too large and would overflow"); ``` The fix has not been added to the Rust registry at the time of publish.

Cybersecurity researchers have discovered five vulnerabilities in Fluent Bit, an open-source and lightweight telemetry agent, that could be chained to compromise and take over cloud infrastructures. The security defects "allow attackers to bypass authentication, perform path traversal, achieve remote code execution, cause denial-of-service conditions, and manipulate tags," Oligo Security said in

## Summary Heap buffer overflow in `mlx::core::load()` when parsing malicious NumPy `.npy` files. Attacker-controlled file causes 13-byte out-of-bounds read, leading to crash or information disclosure. Environment: - OS: Ubuntu 20.04.6 LTS - Compiler: Clang 19.1.7 ## Vulnerability The parser reads a 118-byte header from the file, but line 268 uses `std::string(&buffer[0])` which stops at the first null byte, creating a 20-byte string instead. Then line 276 tries to read `header[34]` without checking the length first, reading 13 bytes past the allocation. **Location**: `mlx/io/load.cpp:268,276` **Bug #1** (line 268): ```cpp std::string header(&buffer[0]); // stops at first null byte ``` **Bug #2** (line 276): ```cpp bool col_contiguous = header[34] == 'T'; // No bounds check ``` ## Possible Fix ```cpp // Line 268 std::string header(&buffer[0], header_len); // Line 276 if (header.length() < 35) throw std::runtime_error("Malformed header"); ``` ## PoC ```bash pip install mlx...

Google has disclosed that the company's continued adoption of the Rust programming language in Android has resulted in the number of memory safety vulnerabilities falling below 20% for the first time. "We adopted Rust for its security and are seeing a 1000x reduction in memory safety vulnerability density compared to Android’s C and C++ code. But the biggest surprise was Rust's impact on
