Overview
curl is a command line tool and library for transferring data with URL syntax, supporting DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT, POP3, POP3S, RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET and TFTP. libcurl offers a myriad of powerful features.
Affected versions of this package are vulnerable to Out-of-bounds Read due to the improper handling of a buffer during the punycode conversion process in the curl_url_get function, by providing a specially crafted input of exactly 256 bytes.
Note: This is only exploitable if the system is configured to use the macidn IDN backend.
