What is CVE-2016-4490?

An integer overflow vulnerability in the cp-demangle.c file of the libiberty component of GCC can be exploited by remote attackers. By crafting a specific binary, an attacker can trigger a denial of service condition, leading to segmentation faults and crashes. This issue arises from inconsistent handling of type lengths, particularly between long and int types, which may lead to serious instability and service disruption when analyzing untrusted binaries.
