CVE-2020-7069 Open this link in a new tabHow to fix?
Upgrade SLES:15.2 php7-ctype to version 7.4.6-3.11.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream php7-ctype package and not the php7-ctype package as distributed by SLES.
See How to fix? for SLES:15.2 relevant fixed versions and status.
In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data.
