Fortinet's FortiGuard Labs has discovered a remote denial of service vulnerability in MongoDB.
MongoDB is an open-source document-oriented database for multiple platforms, which provides high performance, high availability and automatic scaling. Compared with the traditional table-based relational database structure, MongoDB takes advantage of JSON-like documents with dynamic schemas, making the integration of data in certain types of applications easier and faster.
The vulnerability is caused due to incorrectly handling a specially-crafted regex string. It allows remote attackers to launch a denial of service attack.
FortiGuard Labs released the following FortiGate IPS signature which covers this specific vulnerability:

Users should apply the solution provided by MongoDB.
This vulnerability actually resides in the very old 3rd-party PCRE library (http://www.pcre.org/),
which was released 3 years ago, but still used in MongoDB.
This vulnerability was discovered by Kai Lu of Fortinet's FortiGuard Labs.
