CVE-2014-5461
Buffer overflow in the vararg functions in ldo.c in Lua 5.1 through 5.2.x before 5.2.3 allows context-dependent attackers to cause a denial of service (crash) via a small number of arguments to a function with a large number of fixed arguments.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 12.0%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
