La etiqueta propia de Trivy es CRITICAL. Crítica según NVD, Bitnami. Más baja según Red Hat (alta), AlmaLinux (alta), Amazon (alta), Oracle (alta), Rocky Linux (alta), Ubuntu (media).

Descripción

In PHP versions 8.4.* before 8.4.21 and 8.5.* before 8.5.6, when an encoding name containing an embedded NUL byte is passed to mb_convert_encoding() or related mbstring functions, the code incorrectly assumes that when strncasecmp() returns 0 it means the strings have the same length. This can lead to out-of-bounds read of global memory, potentially causing a crash or information disclosure or crash. Affected functions include mb_convert_encoding(), mb_detect_encoding(), mb_convert_variables(), and mb_detect_order(), as well as the mbstring.detect_order and mbstring.http_output INI settings.
