Multiple use-after-free vulnerabilities in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13 allow remote attackers to execute arbitrary code via vectors related to (1) the Serializable interface, (2) the SplObjectStorage class, and (3)…
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 46.8%, higher than 99% of all known CVEs. Patch or mitigate before the next change window.
