- Summary
- CVE-2021-22925 affecting package curl for versions less than 7.76.0-5
- Details
-
curl supports the
-tcommand line option, known asCURLOPT_TELNETOPTIONSin libcurl. This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sendingNEW_ENVvariables, 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. - References
