Name of the Vulnerable Software and Affected Versions
PHP versions prior to 5.5.34
PHP versions 5.6.x prior to 5.6.20
PHP versions 7.x prior to 7.0.5
Description
The issue is caused by multiple integer overflows in the
mbfl strcut function in PHP. This can be exploited by remote attackers to cause a denial of service, resulting in the application crashing, or possibly to execute arbitrary code via a crafted mb strcut call.Recommendations
For PHP versions prior to 5.5.34, update to version 5.5.34 or later.
For PHP versions 5.6.x prior to 5.6.20, update to version 5.6.20 or later.
For PHP versions 7.x prior to 7.0.5, update to version 7.0.5 or later.
As a temporary workaround, consider restricting the use of the
mb strcut function until a patch is available.Exploit
