Descriptions

Integer overflow vulnerability in tool_operate.c in curl 7.65.2 via a large value as the retry delay. NOTE: many parties report that this has no direct security impact on the curl user; however, it may (in theory) cause a denial of service to associated systems or networks if, for example, --retry-delay is misinterpreted as a value much smaller than what was intended. This is not especially plausible because the overflow only happens if the user was trying to specify that curl should wait weeks (or longer) before trying to recover from a transient error.

Vulnerabilidad de desbordamiento de enteros en "tool_operate.c" en curl v7.65.2 a través de un valor grande como retardo de reintento. NOTA: muchas partes informan de que esto no tiene un impacto directo en la seguridad del usuario de curl: sin embargo, puede (en teoría) causar una denegación de servicio a sistemas o redes asociados si, por ejemplo, --retry-delay se malinterpreta como un valor mucho menor del que se pretendía. Esto no es especialmente plausible porque el desbordamiento sólo ocurre si el usuario estaba intentando especificar que curl debería esperar semanas (o más) antes de intentar recuperarse de un error transitorio.
