CVE−2022-3602 이게 뭔가요? 이 문서와 저장소는 OpenSSL의 punycode 버퍼 오버플로 문제인 CVE−2022-3602에 대한 분석입니다. '안티-POC'이 문제는 악용 가능성이 없는 것으로 보입니다로, 자체 OpenSSL 빌드를 유지 관리하는 사람들과 컴파일러 유지 관리자를 위한 것입니다. 동일 릴리스에는 별도의 CVE인 CVE-2022-3786이 있으며, 이 역시 버퍼 오버플로를 유발하지만 공격자가 그 내용을 제어할 수 없습니다. 여기에는 해당 문제에 대한 재현이 없지만, 해당 문제는 충돌로 인한 서비스...
netty: Netty: High integrity impact due to improper DNS domain name constraint enforcement
A flaw was found in Netty. Netty's DNS Domain Name System codec does not properly enforce domain name constraints as defined in RFC 1035 during both encoding and decoding processes. This vulnerability allows a remote attacker to exploit the decoder using malicious DNS responses or exploit the...
CVE-2026-69248
cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 49.0.0, if an intermediate constrained CA permits the DNS name foo.example.com, and the leaf certificate has a wildcard in its DNS SAN of .example.com, python-cryptography's verifier...
