## 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.
