Description Josh Bressers 2010-06-18 09:09:39 EDT
A vulnerability was found in the SplObjectStorage unserializer.  If the PHP
unserialize() function is used by a script on untrusted data provided by a
remote attacker the attacker may be able to force an information leak or
remote execution of code on the server.

This was reported by Stefan Esser at the SyScan'10 Conference in Singapore.
