CVE-2021-22898

Status Candidate

Overview

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.

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 5894-1 - Harry Sintonen and Tomas Hoger discovered that curl incorrectly handled TELNET connections when the -t option was used on the command line. Uninitialized data possibly containing sensitive information could be sent to the remote server, contrary to expectations. This issue was only fixed in Ubuntu 14.04 ESM. It was discovered that curl incorrectly handled denials when using HTTP proxies. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code.
