CVE-2014-3597

Name of the Vulnerable Software and Affected Versions PHP versions prior to 5.4.32 PHP versions 5.5.x prior to 5.5.16

Description The issue is related to multiple buffer overflows in the php parserr function, which can be exploited by remote DNS servers using crafted DNS records. This can lead to a denial of service (application crash) or possibly the execution of arbitrary code. The dns get record and dn expand functions are involved in this issue.

Recommendations For PHP versions prior to 5.4.32, update to version 5.4.32 or later. For PHP versions 5.5.x prior to 5.5.16, update to version 5.5.16 or later. As a temporary workaround, consider restricting access to the dns get record and dn expand functions until a patch is available.
