- curl vulnerabilities
- Details
-
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. (CVE-2021-22898, CVE-2021-22925)
Harry Sintonen discovered that curl incorrectly reused connections in the connection pool. This could result in curl reusing the wrong connections. (CVE-2021-22924)
