Debian LTS Advisory DLA-2664-1 [email protected]
https://www.debian.org/lts/security/ Sylvain Beucler
May 17, 2021 https://wiki.debian.org/LTS
Package : curl
Version : 7.52.1-5+deb9u14
CVE ID : CVE-2021-22876
Debian Bug : 986269
Viktor Szakats reported that libcurl, an URL transfer library, does
not strip off user credentials from the URL when automatically
populating the Referer HTTP request header field in outgoing HTTP
requests. Sensitive authentication data may leak to the server that is
the target of the second HTTP request.
For Debian 9 stretch, this problem has been fixed in version
7.52.1-5+deb9u14.
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
