SOL29154575 - ImageMagick vulnerability CVE-2016-3717

Description

Vulnerability Recommended Actions If you are running a version listed in the **Versions known to be vulnerable** column, you can eliminate this vulnerability by upgrading to a version listed in the **Versions known to be not vulnerable** column. If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists. BIG-IP/BIG-IQ/Enterprise Manager To mitigate this vulnerability, you can disable the vulnerable **ImageMagick** coders in the global policy file **/etc/ImageMagick/policy.xml**. To do so, perform the following procedure: **Impact of action:** Performing the following procedure should not have a negative impact on your system. 1. Log in to the command line of the affected system. 2. Back up the **ImageMagick **global policy file by typing the following command: cp -p /etc/ImageMagick/policy.xml /var/tmp/policy.xml.sol29154575 3. Edit the **ImageMagick **global policy file using a text editor of your choice, for example **vi**. 4. Include the vulnerable **ImageMagick **coders in the **policymap** stanza. For example, if the **LABEL** coder is vulnerable, you would include the following line in the **policymap** stanza: <policy domain="coder" rights="none" pattern="LABEL" /> Since the vulnerable coder listed in CVE-2016-3717 is LABEL, the modified **policymap** stanza should look similar to the following example: <policymap> <policy domain="coder" rights="none" pattern="LABEL" /> </policymap> 5. Save the changes and exit the text editor.
