A vulnerbailty was found in curl, a command line tool for transferring data with URL syntax.
When using when using -J (–remote-header-name) and -i (–include) in the same command line, a malicious server could force curl to overwrite the contents of local files with incoming HTTP headers.
For Debian 9 stretch, this problem has been fixed in version 7.52.1-5+deb9u11.
We recommend that you upgrade your curl packages.
For the detailed security status of curl please refer to its security tracker page at: https://security-tracker.debian.org/tracker/curl
