CVE-2019-9022 (opens in a new tab)How to fix?
Upgrade Debian:8 php5 to version 5.6.40+dfsg-0+deb8u2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream php5 package and not the php5 package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
An issue was discovered in PHP 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.2. dns_get_record misparses a DNS response, which can allow a hostile DNS server to cause PHP to misuse memcpy, leading to read operations going past the buffer allocated for DNS data. This affects php_parserr in ext/standard/dns.c for DNS_CAA and DNS_ANY queries.
