cURL is a computer software project providing a library (libcurl) and command-line tool (curl) for transferring data using various protocols.
Security Fix(es):
curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPTSSLCIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport security significantly.(CVE-2021-22897)
curl 7.7 through 7.76.1 suffers from an information disclosure when the -t
command line option, known as CURLOPT_TELNETOPTIONS
in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol.(CVE-2021-22898)
