Highlights
Cryptographic Issues: 7 prior fixes. Scrutinize any change in this area.
authenc.cpp: most-fixed (3 issues). Treat as high-risk during review.
17 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Cryptographic Issues: ElGamal encryption parameter handling was historically vulnerable to cryptographic degradation due to using an estimated work factor instead of the proper subgroup order (CVE-2021-40530).
Memory Corruption: Platforms utilizing AltiVec/Power8 vectors suffer from wild memory writes unless SIMD buffers are enforced to be strictly aligned using specialized types such as AlignedSecByteBlock.
Side-Channel Information Leak: Elliptic curve algorithms (ECP) are highly susceptible to timing and side-channel leakage during fundamental arithmetic operations such as Add and Double unless complete addition formulas are utilized.
