概要
OpenSSL often sits below the application dependency stack: in container layers, build scripts, C/C++ dependency managers, firmware images, appliances, and host packages. CVE-2025-15467 is tied to CMS message parsing in affected OpenSSL release lines, so repo evidence should drive a runtime upgrade and deployment review before anyone treats the issue as confirmed exploitability.
仕組み
The repo check looks for explicit OpenSSL version evidence in Dockerfiles, Conan files, CMake/build metadata, vcpkg metadata, and build scripts. It maps the observed version to OpenSSL's affected and fixed branch ranges, and it can attach CMS or S/MIME usage hints when those appear in source or configuration. The finding stays scoped to source/config evidence and does not claim FixVibe ran OpenSSL, parsed malformed CMS content, observed a crash, or proved code execution.
被害範囲
If an affected OpenSSL runtime is the one deployed and it parses untrusted CMS AuthEnvelopedData or EnvelopedData content, malformed AEAD parameter handling may cross a stack memory-safety boundary. A repo match should trigger branch-aware OpenSSL remediation, artifact rebuilds, and runtime inventory before it is treated as production exposure.

鉄壁の防御
Upgrade the active OpenSSL branch to 3.6.1, 3.5.5, 3.4.4, 3.3.6, 3.0.19, or a vendor-patched equivalent. Rebuild every statically linked binary, container image, firmware/appliance package, and host package that carries OpenSSL, then verify the deployed runtime version directly. Review CMS and S/MIME ingestion paths with benign fixtures while avoiding crash reproduction as a verification method.
