CVE-2021-22925

CVE-2021-22925 affects curl/libcurl’s TELNET OPTION handling (-t / CURLOPT_TELNETOPTIONS). A flaw in the option parser for NEW_ENV variables can cause uninitialized data from a stack buffer to be sent to the server, due to incorrect sscanf usage when parsing the provided string. This could reveal...

CVE-2021-22925

curl supports the -t command line option, known as CURLOPTTELNETOPTIONSin libcurl. This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sending NEWENV variables, libcurlcould be made to pass on uninitialized data from a stack based...

CVE-2021-22926

libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the CURLOPTSSLCERT option --cert with the command line tool.When libcurl is built to use the macOS native TLS library Secure Transport, an application can ask for the client certificat...
