CVE-2016-5080 is a critical integer overflow vulnerability in the rtxMemHeapAlloc function of Objective Systems ASN1C for C/C++ versions prior to 7.0.2. This flaw allows unauthenticated attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow) by providing specially crafted ASN.1 data to applications compiled with the affected library. With a CVSS score of 9.8 (CRITICAL), it presents a severe risk due to its network-exploitable nature, low attack complexity, and high impact on confidentiality, integrity, and availability. While there are no known public exploits (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered significant community discussion and media coverage, indicating awareness and potential for future exploitation.
