CVE-2015-9096
SMTP command injection in Net::SMTP via CRLF sequences in a RCPT TO or MAIL FROM command.
CVE-2016-2339
Exploitable heap overflow in Fiddle::Function.new.
CVE-2016-7798
Incorrect handling of initialization vector in the GCM mode in the OpenSSL extension.
CVE-2017-0898
Buffer underrun vulnerability in Kernel.sprintf.
CVE-2017-0899
ANSI escape sequence vulnerability in RubyGems.
CVE-2017-0900
DoS vulnerability in the RubyGems query command.
CVE-2017-0901
gem installer allowed a malicious gem to overwrite arbitrary files.
CVE-2017-0902
RubyGems DNS request hijacking vulnerability.
CVE-2017-0903
Max Justicz reported that RubyGems is prone to an unsafe object deserialization vulnerability. When parsed by an application which processes gems, a specially crafted YAML formatted gem specification can lead to remote code execution.
CVE-2017-10784
Yusuke Endoh discovered an escape sequence injection vulnerability in the Basic authentication of WEBrick. An attacker can take advantage of this flaw to inject malicious escape sequences to the WEBrick log and potentially execute control characters on the victim's terminal emulator when reading logs.
CVE-2017-14033
asac reported a buffer underrun vulnerability in the OpenSSL extension. A remote attacker could take advantage of this flaw to cause the Ruby interpreter to crash leading to a denial of service.
CVE-2017-14064
Heap memory disclosure in the JSON library.
CVE-2017-17405
A command injection vulnerability in Net::FTP might allow a malicious FTP server to execute arbitrary commands.
CVE-2017-17742
Aaron Patterson reported that WEBrick bundled with Ruby was vulnerable to an HTTP response splitting vulnerability. It was possible for an attacker to inject fake HTTP responses if a script accepted an external input and output it without modifications.
CVE-2017-17790
A command injection vulnerability in lib/resolv.rb's lazy_initialze might allow a command injection attack. However untrusted input to this function is rather unlikely.
CVE-2018-6914
ooooooo_q discovered a directory traversal vulnerability in the Dir.mktmpdir method in the tmpdir library. It made it possible for attackers to create arbitrary directories or files via a .. (dot dot) in the prefix argument.
CVE-2018-8777
Eric Wong reported an out-of-memory DoS vulnerability related to a large request in WEBrick bundled with Ruby.
CVE-2018-8778
aerodudrizzt found a buffer under-read vulnerability in the Ruby String#unpack method. If a big number was passed with the specifier @, the number was treated as a negative value, and an out-of-buffer read occurred. Attackers could read data on heaps if an script accepts an external input as the argument of String#unpack.
CVE-2018-8779
ooooooo_q reported that the UNIXServer.open and UNIXSocket.open methods of the socket library bundled with Ruby did not check for NUL bytes in the path argument. The lack of check made the methods vulnerable to unintentional socket creation and unintentional socket access.
CVE-2018-8780
ooooooo_q discovered an unintentional directory traversal in some methods in Dir, by the lack of checking for NUL bytes in their parameter.
CVE-2018-1000075
A negative size vulnerability in ruby gem package tar header that could cause an infinite loop.
CVE-2018-1000076
RubyGems package improperly verifies cryptographic signatures. A mis-signed gem could be installed if the tarball contains multiple gem signatures.
CVE-2018-1000077
An improper input validation vulnerability in RubyGems specification homepage attribute could allow malicious gem to set an invalid homepage URL.
CVE-2018-1000078
Cross Site Scripting (XSS) vulnerability in gem server display of homepage attribute.
CVE-2018-1000079
Path Traversal vulnerability during gem installation.
For Debian 8 'Jessie', these problems have been fixed in version 2.1.5-2+deb8u4.
We recommend that you upgrade your ruby2.1 packages.

Applications inspecting\ngem files without installing them can be tricked to execute arbitrary code\nin the context of the ruby interpreter. (CVE-2017-0903)\n\n * It was found that WEBrick did not sanitize all its log messages. If logs\nwere printed in a terminal, an attacker could interact with the terminal\nvia the use of escape sequences.

A remote attacker\ncould exploit this flaw to execute arbitrary commands by setting up a\nmalicious FTP server and tricking a user or Ruby application into\ndownloading files with specially crafted names using the Net::FTP\nmodule. (CVE-2017-17405)\n\n* A buffer underflow was found in ruby's sprintf function. An\nattacker, with ability to control its format string parameter, could\nsend a specially crafted string that would disclose heap memory or\ncrash the interpreter. (CVE-2017-0898)\n\n* It was found that rubygems did not sanitize gem names during\ninstallation of a given gem. A specially crafted gem could use this\nflaw to install files outside of the regular directory.\n(CVE-2017-0901)\n\n* A vulnerability was found where rubygems did not sanitize DNS\nresponses when requesting the hostname of the rubygems server for a\ndomain, via a _rubygems._tcp DNS SRV query. An attacker with the\nability to manipulate DNS responses could direct the gem command\ntowards a different domain. (CVE-2017-0902)\n\n* A vulnerability was found where the rubygems module was vulnerable\nto an unsafe YAML deserialization when inspecting a gem. Applications\ninspecting gem files without installing them can be tricked to execute\narbitrary code in the context of the ruby interpreter. (CVE-2017-0903)\n\n* It was found that WEBrick did not sanitize all its log messages. If\nlogs were printed in a terminal, an attacker could interact with the\nterminal via the use of escape sequences. (CVE-2017-10784)\n\n* It was found that the decode method of the OpenSSL::ASN1 module was\nvulnerable to buffer underrun. An attacker could pass a specially\ncrafted string to the application in order to crash the ruby\ninterpreter, causing a denial of service. (CVE-2017-14033)\n\n* A vulnerability was found where rubygems did not properly sanitize\ngems' specification text. A specially crafted gem could interact with\nthe terminal via the use of escape sequences. (CVE-2017-0899)\n\n* It was found that rubygems could use an excessive amount of CPU\nwhile parsing a sufficiently long gem summary. A specially crafted gem\nfrom a gem repository could freeze gem commands attempting to parse\nits summary. (CVE-2017-0900)\n\n* A buffer overflow vulnerability was found in the JSON extension of\nruby. An attacker with the ability to pass a specially crafted JSON\ninput to the extension could use this flaw to expose the interpreter's\nheap memory. (CVE-2017-14064)\n\n* The 'lazy_initialize' function in lib/resolv.rb did not properly\nprocess certain filenames.

So, if a script accepts an external input as the argument of String#unpack, the attacker can read data on heaps.\n\nCVE-2018-8779: Unintentional socket creation by poisoned NUL byte in UNIXServer and UNIXSocket\n\nUNIXServer.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.\nSo, if a script accepts an external input as the argument of this method, the attacker can accepts the socket file in the unintentional path.\n\nCVE-2018-8780: Unintentional directory traversal by poisoned NUL byte in Dir\n\nDir.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.
