TITLE

curl  Vulnerability in resource initialization deficiency in

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. curl Exists in a flaw in resource initialization.Information may be obtained. Summary: An update is now available for OpenShift Logging 5.2.
