Vulnerabilidades

mod_access.c in lighttpd 1.4.15 ignores trailing / (slash) characters in the URL, which allows remote attackers to bypass url.access-deny settings.

lighttpd 1.4.15, when run on 32 bit platforms, allows remote attackers to cause a denial of service (daemon crash) via unspecified vectors involving the use of incompatible format specifiers in certain debugging messages in the (1) mod_scgi, (2) mod_fastcgi, and (3) mod_webdav modules.

connections.c in lighttpd before 1.4.16 might accept more connections than the configured maximum, which allows remote attackers to cause a denial of service (failed assertion) via a large number of connection attempts.

lighttpd 1.4.12 and 1.4.13 allows remote attackers to cause a denial of service (cpu and resource consumption) by disconnecting while lighttpd is parsing CRLF sequences, which triggers an infinite loop and file descriptor consumption.

lighttpd before 1.4.14 allows attackers to cause a denial of service (crash) via a request to a file whose mtime is 0, which results in a NULL pointer dereference.

response.c in Lighttpd 1.4.10 and possibly previous versions, when run on Windows, allows remote attackers to read arbitrary source code via requests that contain trailing (1) "." (dot) and (2) space characters, which are ignored by Windows, as demonstrated by PHP files.

LightTPD 1.4.8 and earlier, when the web root is on a case-insensitive filesystem, allows remote attackers to bypass URL checks and obtain sensitive information via file extensions with unexpected capitalization, as demonstrated by a request for index.PHP when the configuration invokes the PHP interpreter only for…

The buffer_urldecode function in Lighttpd 1.3.7 and earlier does not properly handle control characters, which allows remote attackers to obtain the source code for CGI and FastCGI scripts via a URL with a %00 (null) character after the file extension.

Buffer overflow in the Log function in util.c in GazTek ghttpd 1.4 through 1.4.3 allows remote attackers to execute arbitrary code via a long HTTP GET request.

Buffer overflows in GazTek ghttpd 1.4 allows a remote attacker to execute arbitrary code via long arguments that are passed to (1) the Log function in util.c, or (2) serveconnection in protocol.c.
