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 7.3.x below 7.3.29, 7.4.x below 7.4.21 and 8.0.x below 8.0.8, when using Firebird PDO driver extension, a malicious database server could cause crashes in various database functions, such as getAttribute(), execute(), fetch() and others by returning invalid response data that is not parsed correctly by the driver. This can result in crashes, denial of service or potentially memory corruption.
