Description

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.

Affected configurations

• haxx curl (>= 7.7 <= 7.76.1) • debian debian linux 9.0 • fedoraproject fedora 33 • fedoraproject fedora 34 • oracle communications cloud native core binding support function 1.11.0 • oracle communications cloud native core network function cloud native environment 1.10.0 • oracle communications cloud native core network repository function 1.15.0 • oracle communications cloud native core network repository function 1.15.1 • oracle communications cloud native core network slice selection function 1.8.0 • oracle communications cloud native core service communication proxy 1.15.0 • oracle essbase (< 11.1.2.4.047) • oracle essbase (>= 21.0 < 21.3) • oracle mysql server (< 5.7.34) • oracle mysql server (>= 8.0.15 < 8.0.25) • siemens sinec infrastructure network services (< 1.0.1.1) • splunk universal forwarder (>= 8.2.0 < 8.2.12) • splunk universal forwarder (>= 9.0.0 < 9.0.6) • splunk universal forwarder 9.1.0
