9.8
CRITICAL · CVSS 3.0 · EPSS 10.1% (pctl 96)
Patch early
EPSS 10.1% — above the 10% action threshold.
Description
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.
