-Check debug symbols are present in shared object and can identify
-code.
-
-It starts scanning from a directory and recursively scans all ELF
-files found in it for various symbols to ensure all debuginfo is
-present and nothing has been stripped.

-Usage:

-./check-debug-symbols /path/of/dir/to/scan/

-Subject: [PATCH] Revert "Disable implicit rejection for RSA PKCS#1 (#95218)"
-
-This reverts commit e3500b8e8ad18e8bf067dc5250863b64bb8f0de0.
-
-To quote Clemens Lang:
-
-> [Disabling implcit rejection] re-enables a Bleichenbacher timing oracle
-> attack against PKCS#1v1.5 decryption. See
-> https://people.redhat.com/~hkario/marvin/ for details and
-> https://github.com/dotnet/runtime/pull/95157#issuecomment-1842784399 for a
-> comment by the researcher who published the vulnerability and proposed the
-> change in OpenSSL.
-
-For more details, see:
-https://github.com/dotnet/runtime/pull/95216#issuecomment-1842799314
