Python · Pickle · CVE-2012-4406
**Name of the Vulnerable Software and Affected Versions**
OpenStack Object Storage (swift) versions prior to 1.7.0
**Description**
The issue allows remote attackers to execute arbitrary code via a crafted pickle object. This is due to the unsafe use of the loads function in the pickle Python module when storing and loading metadata in memcached.
**Recommendations**
For versions prior to 1.7.0, update to version 1.7.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the memcached metadata storage to minimize the risk of exploitation.
