CVE-2024-12133
Estado: AplazadaMedia (5.3)—
A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack.

"value": "A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack."

Al procesar una gran cantidad de elementos en un certificado, libtasn1 tarda mucho más de lo esperado, lo que puede ralentizar o incluso bloquear el sistema. Esta falla permite que un atacante envíe un certificado especialmente manipulado, lo que provoca un ataque de denegación de servicio."
