CVE-2013-6422 Open this link in a new tabHow to fix?
Upgrade Debian:12 curl to version 7.34.0-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
The GnuTLS backend in libcurl 7.21.4 through 7.33.0, when disabling digital signature verification (CURLOPT_SSL_VERIFYPEER), also disables the CURLOPT_SSL_VERIFYHOST check for CN or SAN host name fields, which makes it easier for remote attackers to spoof servers and conduct man-in-the-middle (MITM) attacks.
