  Elkhorn Slough
On summer nights at the end of the last millennium, the eyeshine of hundreds of CRLF could be seen in the beam of a flashlight, and the waters teemed with their tadpole young.
Nina and Valentine also found that CRLF were absent from the most nutrient-enriched ponds (of which there were a few, probably due to agricultural inputs), and that ponds throughout the region were infected with the chytrid fungus.
The white dots are freshwater ponds; the yellow dots are freshwater ponds with populations of CRLF.

CRLF Injection by Ulf Harnhammar "They crowded up to Lenin with their noses worn off / A handshake is worthy if it's all that you've got" -- R.E.M., "Harborcoat" Carriage Return (CR, ASCII code 13) and Line Feed (LF, ASCII code 10) are two commonly used non-printing ASCII characters.
If the CR and LF characters are not removed from the input that is used to put together the commands, we can send off several commands at the same time, where all but the first one are made up by us and just passed on.
It all depends on whether this flaw allows the user to do something he or she should not be able to do.

 CRLF Injection - OWASP
For example: in Windows both a CR and LF are required to note the end of a line, whereas in Linux/UNIX a LF is only required.
Another example is the "response splitting" attacks, where CRLF's is injected into an application and included in the response.
The extra CRLF's are interpreted by proxies, caches, and maybe browsers as the end of a packet, causing mayhem.

crlf converts among the different end-of-line formats for unix, dos, and mac.
The C version is a single program that does in-place editing and works with stdin and stdout and is designed to account for asynchronous signals.
Instead of having a single integrated program, the conversion routines are spread across three programs, "crlf", "lf", and "cr".

The problem is that unix expects linebreaks in the 'LF' format (\n), while Windows expects them in the 'CRLF' format (\r\n).
In this way, whenever any program thinks it is launching notepad, it will really be launching the CRLF wrapper first.

 CRLF injection attacks: How they work and what to do about them   (Site not responding. Last check: 2007-11-06)
CRLF injection attacks are not as well known as some other attacks, but when used against vulnerable applications, CRLF injections can be just as effective (for the attacker) and devastating (for you).
CRLF stands for "carriage return / line feed," which are two ASCII characters (ASCII 13 and 10 respectively).
An attacker can execute a CRLF injection by putting a CRLF sequence in a piece of data to change how that data is handled by the program receiving it.

 David Wang : HTTP.SYS rejection of request lines not terminated by CRLF
CRLF, bare CR, and bare LF as being representative of a line break in
Thus, the first double CRLF encountered in an HTTP request demarcates request "headers" from the entity body.
Request entity body can be anything you want, and this is what your paragraph refers to (media content has to refer to the entity-body, which is what is being transported -- request headers are NOT what is being transported by HTTP; they are metadata that merely describe the entity body).

CRLF is a handy utility for converting UNIX text files with a single byte carriage return line feed combination into something your PC editor can better handle - or vice versa.
UNIX normally assumes that the line feed character (0Ah) means both carriage return and line feed, whereas many PC based editors and applications do not.
CRLF will not touch your original file, but will output to a new file with the extension 'CRLF'.

 CRLF - How to find & fix CRLF injection
A CRLF Injection attack occurs when a hacker manages to inject CRLF Commands into the system.
Even if attackers find a website open to CRLF Injection, they are limited to how the application structure is built and to how severe the flaw in the system is.
In this case, since the input is not being properly filtered from the CR and LF characters, the user created a fake entry in the log file.

 Lynx CRLF Injection
TECHNICAL DETAILS: When a URL is given on the command line or in the WWW_HOME environment variable, Lynx doesn't remove or encode dangerous characters such as space, tab, CR and LF before constructing HTTP queries.
One scenario is when a program starts Lynx, and the host part of the URL is supplied by the program and the path by its user (something like "lynx http://www.site3.st/$path", where the value of $path is defined by the user).

Internet Explorer considers the CRLF characters to be end-of-file markers, but other programs might not handle the CRLF characters correctly when they parse a text document.

These characters may be present because Internet Explorer may add a CRLF character each time that you save the document.
