CVE-2025-58050

The PCRE2 library is a set of C functions that implement regular expression pattern matching. In version 10.45, a heap-buffer-overflow read vulnerability exists in the PCRE2 regular expression matching engine, specifically within the handling of the (*scs:...) (Scan SubString) verb when combined with (*ACCEPT) in src/pcre2_match.c. This vulnerability may potentially lead to information disclosure if the out-of-bounds data read during the memcmp affects the final match result in a way observable by the attacker. This issue has been resolved in version 10.46.

Summary		(es) La librería PCRE2 es un conjunto de funciones de C que implementan la coincidencia de patrones con expresiones regulares. En la versión 10.45, existe una vulnerabilidad de lectura por desbordamiento de búfer de montón en el motor de coincidencia de expresiones regulares de PCRE2, específicamente en la gestión del verbo (scs:...) (Scan SubString) al combinarse con (ACCEPT) en src/pcre2_match.c. Esta vulnerabilidad podría provocar la divulgación de información si los datos fuera de los límites leídos durante la memcmp afectan el resultado final de la coincidencia de forma observable para el atacante. Este problema se ha resuelto en la versión 10.46.
