NVD Description

Note: Versions mentioned in the description apply only to the upstream php-pecl-xdebug-debugsource package and not the php-pecl-xdebug-debugsource package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

When using certain mbstring functions to convert multibyte encodings, in PHP versions 7.2.x below 7.2.27, 7.3.x below 7.3.14 and 7.4.x below 7.4.2 it is possible to supply data that will cause function mbfl_filt_conv_big5_wchar to read past the allocated buffer. This may lead to information disclosure or crash.
