Ruby news:

+
CVE-2017-17742: HTTP response splitting in WEBrick
+
If a script accepts an external input and outputs it without + modification as a part of HTTP responses, an attacker can use newline + characters to deceive the clients that the HTTP response header is + stopped at there, and can inject fake HTTP responses after the newline + characters to show malicious contents to the clients.
+
CVE-2018-6914: Unintentional file and directory creation with + directory traversal in tempfile and tmpdir
+
Dir.mktmpdir method introduced by tmpdir library accepts the prefix + and the suffix of the directory which is created as the first parameter. + The prefix can contain relative directory specifiers "../", so this + method can be used to target any directory. So, if a script accepts an + external input as the prefix, and the targeted directory has + inappropriate permissions or the ruby process has inappropriate + privileges, the attacker can create a directory or a file at any + directory.
+
CVE-2018-8777: DoS by large request in WEBrick
+
If an attacker sends a large request which contains huge HTTP headers, + WEBrick try to process it on memory, so the request causes the + out-of-memory DoS attack.
+
CVE-2018-8778: Buffer under-read in String#unpack
+
String#unpack receives format specifiers as its parameter, and can + be specified the position of parsing the data by the specifier @. If a + big number is passed with @, the number is treated as the negative + value, and out-of-buffer read is occurred. So, if a script accepts an + external input as the argument of String#unpack, the attacker can read + data on heaps.
+
CVE-2018-8779: Unintentional socket creation by poisoned NUL byte in + UNIXServer and UNIXSocket
+
UNIXServer.open accepts the path of the socket to be created at the + first parameter. If the path contains NUL (\0) bytes, this method + recognize that the path is completed before the NUL bytes. So, if a + script accepts an external input as the argument of this method, the + attacker can make the socket file in the unintentional path. And, + UNIXSocket.open also accepts the path of the socket to be created at + the first parameter without checking NUL bytes like UNIXServer.open. + So, if a script accepts an external input as the argument of this + method, the attacker can accepts the socket file in the unintentional + path.
+
CVE-2018-8780: Unintentional directory traversal by poisoned NUL byte + in Dir
+
Dir.open, Dir.new, Dir.entries and Dir.empty? accept the path of the + target directory as their parameter. If the parameter contains NUL (\0) + bytes, these methods recognize that the path is completed before the + NUL bytes. So, if a script accepts an external input as the argument of + these methods, the attacker can make the unintentional directory + traversal.
