Percentile
36.3%
libcurl.so is vulnerable to Improper Certificate Validation. In place of a library’s built-in name matching function, Curl may utilize its own name matching function for TLS. IDN hosts could be mismatched by this private wildcard matching function since they are rendered in a weak form before certificate checks.
