CVE-2015-7511 Open this link in a new tabHow to fix?
Upgrade Debian:12 libgcrypt20 to version 1.6.5-2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libgcrypt20 package and not the libgcrypt20 package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
Libgcrypt before 1.6.5 does not properly perform elliptic-point curve multiplication during decryption, which makes it easier for physically proximate attackers to extract ECDH keys by measuring electromagnetic emanations.
