- Replace unsafe vsprintf() with safer vsnprintf() in Utils.c to prevent possible buffer overflows in gslogError(), gslogMessage(), and gslogMessagePrefix() functions - Fix incorrect variable references in RSA debug logging which prevents compiling debug code. This results in syntax errors: - Use ciphertextLen instead of plaintextLen in RSA.c - Use keyBytesNative instead of pBytes in RSAKey.c - Improve error handling in ockCheckStatus() by using ICC_ERR_error_string_n() with bounded fixed size buffer. Loop printing exception messages changed to print any error code not just the value `1`. - Remove unused OpenSSLError() function from CCM.c These changes enhance security by preventing the potential of a buffer overflow and fix debug logging to display correct variable values.
