CVE-2021-22925
curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl.
Does this matter?
Lower severity and a low EPSS score (4.93%). Track it; it rarely justifies an emergency change on its own.
Description
curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing the string provided by the application.
