CVE-2016-3074
Integer signedness error in GD Graphics Library 2.1.1 (aka libgd or libgd2) allows remote attackers to cause a denial of service (crash) or potentially execute arbitrary code via crafted compressed gd2 data, which triggers a heap-based buffer overflow.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 37.2%, higher than 99% of all known CVEs. Patch or mitigate before the next change window.
