Description

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.

Affected configurations

• php php (>= 7.0.0 < 7.1.26) • php php (>= 7.2.0 < 7.2.14) • php php (>= 7.3.0 < 7.3.2) • debian debian linux 8.0 • debian debian linux 9.0 • canonical ubuntu linux 12.04 • canonical ubuntu linux 14.04 • canonical ubuntu linux 16.04 • netapp storage automation store
