🛡️ GHSA-wwxp-hxh6-8gf8 — binary-vec-io

🟠 CVSS 8.0 — High ✅ No Known Exploit CWE-120 OSV
8.0
CVSS Score
0 Low4 Medium7 High9 Critical10

Description

binary_vec_io access memory out-of-bounds in binary_read_to_ref and binary_write_from_ref

Safe functions accept a single &T or &mut T but multiply by n to create slices extending beyond allocated memory when n > 1.

These functions use from_raw_parts to create slices larger than the underlying allocation, violating memory safety.

The binary_vec_io repository is archived and unmaintained.
