Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 10.1%, higher than 95% of all known CVEs. Patch or mitigate before the next change window.
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.
