Name of the Vulnerable Software and Affected Versions
PHP versions 5.x through 7.1.24
Description
The issue is related to a flaw in the deserialization mechanism of the PHP interpreter, specifically in the ext/standard/var unserializer.c component. This flaw can be exploited by a remote attacker to cause a denial of service (application crash) through an unserialize call for the
com, dotnet, or variant class.Recommendations
For PHP versions 5.x through 7.1.24, update to a version that contains a fix for this issue to prevent exploitation.
As a temporary workaround, consider restricting the use of the
unserialize function for the com, dotnet, or variant class until a patch is available.Exploit
