How to Fix CVE-2012-6532

To remediate this vulnerability, upgrade all affected Zendframework/zendframework1 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

zendframework/zendframework1 fixed: 1.11.13 
Upgrade zendframework/zendframework1 to 1.11.13
zendframework/zendframework1 fixed: 1.12.0 
Upgrade zendframework/zendframework1 to 1.12.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for zendframework/zendframework1

How to Check if You Are Affected

To determine whether your application is affected by CVE-2012-6532, inspect your project dependencies for Zendframework/zendframework1:

inspect dependencies for zendframework/zendframework1

Analyze the terminal output to locate any version of Zendframework/zendframework1 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.11.13), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-776: Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion'), where the product uses xml documents and allows their structure to be defined with a document type definition (dtd), but it does not properly control the number of recursive definitions of entities. In Zendframework/zendframework1, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

(1) `Zend_Dom`, (2) `Zend_Feed`, (3) `Zend_Soap`, and (4) `Zend_XmlRpc` in Zend Framework 1.x before 1.11.13 and 1.12.x before 1.12.0 allow remote attackers to cause a denial of service (CPU consumption) via recursive or circular references in an XML entity definition in an XML DOCTYPE declaration, aka an XML Entity Expansion (XEE) attack.
