Descriptions

An issue was discovered in MediaWiki through 1.36.2. A parser function related to loop control allowed for an infinite loop (and php-fpm hang) within the Loops extension because egLoopsCountLimit is mishandled. This could lead to memory exhaustion.

Se ha detectado un problema en MediaWiki versiones hasta 1.36.2. Una función del analizador relacionada con el control de bucles permitía un bucle infinito (y un cuelgue de php-fpm) dentro de la extensión Loops porque egLoopsCountLimit es manejado inapropiadamente. Esto podía conllevar a un agotamiento de la memoria
