SOL15169: PHP vulnerability CVE-2013-4113

Security Advisory

Original Publication Date: 04/14/2014


ext/xml/xml.c in PHP before 5.3.27 does not properly consider parsing depth, 
which allows remote attackers to cause a denial of service (heap memory 
corruption) or possibly have unspecified other impact via a crafted document 
that is processed by the xml_parse_into_struct function. (CVE-2013-4113)


Authenticated users accessing the Configuration utility may be able to cause 
a DoS by sending crafted XML requests.


F5 Product Development has assigned ID 425194 (BIG-IP), ID 427054 (FirePass), 
ID 456214 (Enterprise Manager) and ID 456217 (BIG-IQ) to this vulnerability.

Recommended action

If the previous table lists a version in the Versions known to be not 
vulnerable column, you can eliminate this vulnerability by upgrading to the 
listed version. If the table does not list any version in the column, then no 
upgrade candidate currently exists.

To mitigate this vulnerability, you should expose the Configuration utility 
only on trusted networks and limit login access to trusted users.
