MEDIUM 6.8EPSS 15.4%

Does this matter?

EPSS puts the probability of exploitation in the next 30 days at 15.4%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.

Description

Multiple buffer overflows in the php_parserr function in ext/standard/dns.c in PHP before 5.4.32 and 5.5.x before 5.5.16 allow remote DNS servers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted DNS record, related to the dns_get_record function and the dn_expand function. NOTE: this issue exists because of an incomplete fix for CVE-2014-4049.
