FreeBSD : php5 -- header splitting attack via carriage-return character (918f38cd-f71e-11e1-8bd8-0022156e8794)

medium Nessus Plugin ID 61782

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Rui Hirokawa reports :

As of PHP 5.1.2, header() can no longer be used to send multiple response headers in a single call to prevent the HTTP Response Splitting Attack. header() only checks the linefeed (LF, 0x0A) as line-end marker, it doesn't check the carriage-return (CR, 0x0D).

However, some browsers including Google Chrome, IE also recognize CR as the line-end.

The current specification of header() still has the vulnerability against the HTTP header splitting attack.

Solution

Update the affected packages.
