{
  "summary": "Reviewed `aws-lc/crypto/x509/v3_int.c`, which only defines X509v3 extension method tables and small ASN.1 integer conversion callbacks for CRL number, delta CRL, and inhibit-any-policy extensions. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this target file.\nReviewed `aws-lc/crypto/mem_test.cc`, which is a gated gtest exercising weak-symbol memory override behavior for `OPENSSL_malloc`, `OPENSSL_free`, `OPENSSL_realloc`, and `CRYPTO_set_mem_functions` on ELF/GNU builds. I found no concrete malicious or supply-chain indicators in the target file: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `include/rust_wrapper.h`, which is a C/C++ header that aggregates AWS-LC/OpenSSL declarations and exposes three exported wrapper prototypes for `ERR_GET_*_RUST`. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed the x86-64 assembly routine for `bignum_mod_p521_9`, which performs a constant-time reduction modulo the P-521 field prime using register arithmetic and ABI save/restore only. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence tampering, or other supply-chain compromise in this target file.\nReviewed `aws-lc/crypto/asn1/a_i2d_fp.c`, which only provides ASN.1-to-BIO/FILE serialization helpers using local heap buffers and OpenSSL error handling. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.",
