Security vulnerabilities and automated fixes for arbitrary code execution issues

A critical set of memory safety vulnerabilities was discovered and patched in `src/try_to_guess_image_fov.c`, a C-based FITS astronomical image processing pipeline. The vulnerabilities — including unsafe string operations, improper memory allocation, and potential integer overflows — created a comprehensive attack surface that could allow an attacker to craft a malicious FITS file and achieve arbitrary code execution. The fix replaces dangerous patterns like `strncpy` with `snprintf`, switches `
A critical heap buffer overflow vulnerability was discovered and patched in `src/opkit_compile.c`, where multiple `memcpy` calls copied user-controlled data into heap-allocated buffers without verifying destination buffer sizes. Left unpatched, this flaw could allow attackers to overwrite heap metadata or function pointers, potentially achieving arbitrary code execution. The fix ensures proper bounds checking before all memory copy operations.
A critical buffer overflow vulnerability was discovered and patched in `libretro_core_options.h`, where unsafe string operations (`strcpy()` and `strcat()`) could allow attackers to corrupt memory and achieve arbitrary code execution. The fix eliminates these dangerous C string functions in favor of bounds-checked alternatives, closing a path that could be exploited through maliciously crafted core option configurations. Understanding this class of vulnerability is essential for any developer wo
A medium-to-high severity vulnerability was discovered and patched in Slidev's resolver module, where dynamically loaded theme and plugin packages specified in slide frontmatter lacked proper validation, allowing a malicious package name to execute arbitrary code with the developer's full OS privileges. This fix addresses a supply-chain-adjacent attack vector that could allow attackers to exfiltrate credentials or compromise developer machines simply by sharing a crafted markdown presentation fi
A high-severity vulnerability in `graphify/hooks.py` allowed attackers to achieve arbitrary code execution on CI/CD runners by injecting malicious hook script paths through a user-controlled configuration file. The fix introduces strict path validation against an allowlist of permitted directories before any subprocess execution. This kind of supply-chain attack vector is increasingly common and can silently compromise entire build pipelines with a single malicious commit.
