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 Exposure of Data Element to Wrong Session via the connection reuse process. An attacker can cause outbound network traffic to be transmitted through an unintended network interface by initiating network requests in an environment where connection pooling is combined with forced local interface binding options. This is only exploitable if the application is configured to use both connection pooling and forced interface prefixes for binding transfers.
