Versionscan is a tool for evaluating your currently installed PHP version and checking it against known CVEs and the versions they were fixed in to report back potential issues.
NOTE: Work is still in progress to adapt the tool to Linux distributions that backport security fixes. As of right now, this only reports back for the straight up version reported.
Installation
{
“require”: {
“psecio/versionscan”: “dev-master”
}
}
The only current dependency is the Symfony console.

To run the scan against your current PHP version, use:
bin/versionscan
The script will check the PHP_VERSION
for the current instance and generate the pass/fail results. The output looks similar to:
Executing against version: 5.4.24
+--------+---------------+------+------------------------------------------------------------------------------------------------------+
| Status | CVE ID | Risk | Summary |
+--------+---------------+------+------------------------------------------------------------------------------------------------------+
| FAIL | CVE-2014-3597 | 6.8 | Multiple buffer overflows in the php_parserr function in ext/standard/dns.c in PHP before 5.4.32 ... |
| FAIL | CVE-2014-3587 | 4.3 | Integer overflow in the cdf_read_property_info function in cdf.c in file through 5.19, as used in... |
Results will be reported back colorized as well to easily show the pass/fail of the check.
There are several parameters that can be given to the tool to configure its scans and results:
If you’d like to define a PHP version to check other than the one the script finds itself, you can use the php-version
parameter:
bin/versionscan scan –php-version=4.3.2
You can also tell the it to only report back the failures and not the passing tests:
bin/versionscan scan –fail-only
You can also sort the results either by the CVE ID or by severity (risk rating), with the sort
parameter and either the “cve” or “risk” value:
bin/versionscan scan –sort=risk
By default versionscan will output information directly to the console in a human-readable result. You can also specify other output formats that may be easier to parse programatically (like JSON). Use the --format
option to change the output:
vendor/bin/versionscan scan –php-version=5.5 –format=json
Supported output formats are console
, json
, xml
and html
.
The HTML output format requires an --output
option of the directory to write the file:
vendor/bin/versionscan scan –php-version=5.5 –format=html –output=/var/www/output
The result will be written to a file named something like versionscan-output-20150808.html
