CVE-2016-5080

Estado: ModificadaCrítica (9.8)—

Integer overflow in the rtxMemHeapAlloc function in asn1rt_a.lib in Objective Systems ASN1C for C/C++ before 7.0.2 allows context-dependent attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow), on a system running an application compiled by ASN1C, via crafted ASN.1 data.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
