CVE-2020-10933 | 4 Debian, Fedoraproject, Linux and 1 more | 4 Debian Linux, Fedora, Linux Kernel and 1 more | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
An issue was discovered in Ruby 2.5.x through 2.5.7, 2.6.x through 2.6.5, and 2.7.0. If a victim calls BasicSocket#read_nonblock(requested_size, buffer, exception: false), the method resizes the buffer to fit the requested size, but no data is copied. Thus, the buffer string provides the previous value of the heap. This may expose possibly sensitive data from the interpreter. | |||||
CVE-2020-10663 | 6 Apple, Debian, Fedoraproject and 3 more | 6 Macos, Debian Linux, Fedora and 3 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through 2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar to CVE-2013-0269, but does not rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead to creation of a malicious object within the interpreter, with adverse effects that are application-dependent. | |||||
CVE-2019-16255 | 4 Debian, Opensuse, Oracle and 1 more | 4 Debian Linux, Leap, Graalvm and 1 more | 2024-11-21 | 6.8 MEDIUM | 8.1 HIGH |
Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows code injection if the first argument (aka the "command" argument) to Shell#[] or Shell#test in lib/shell.rb is untrusted data. An attacker can exploit this to call an arbitrary Ruby method. | |||||
CVE-2019-16254 | 2 Debian, Ruby-lang | 2 Debian Linux, Ruby | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows HTTP Response Splitting. If a program using WEBrick inserts untrusted input into the response header, an attacker can exploit it to insert a newline character to split a header, and inject malicious content to deceive clients. NOTE: this issue exists because of an incomplete fix for CVE-2017-17742, which addressed the CRLF vector, but did not address an isolated CR or an isolated LF. | |||||
CVE-2019-16201 | 2 Debian, Ruby-lang | 2 Debian Linux, Ruby | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
WEBrick::HTTPAuth::DigestAuth in Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 has a regular expression Denial of Service cause by looping/backtracking. A victim must expose a WEBrick server that uses DigestAuth to the Internet or a untrusted network. | |||||
CVE-2019-15845 | 2 Canonical, Ruby-lang | 2 Ubuntu Linux, Ruby | 2024-11-21 | 6.4 MEDIUM | 6.5 MEDIUM |
Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 mishandles path checking within File.fnmatch functions. | |||||
CVE-2019-11879 | 1 Ruby-lang | 1 Webrick | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
The WEBrick gem 1.4.2 for Ruby allows directory traversal if the attacker once had local access to create a symlink to a location outside of the web root directory. NOTE: The vendor states that this is analogous to Options FollowSymlinks in the Apache HTTP Server, and therefore it is "not a problem. | |||||
CVE-2018-8780 | 3 Canonical, Debian, Ruby-lang | 3 Ubuntu Linux, Debian Linux, Ruby | 2024-11-21 | 7.5 HIGH | 9.1 CRITICAL |
In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, the Dir.open, Dir.new, Dir.entries and Dir.empty? methods do not check NULL characters. When using the corresponding method, unintentional directory traversal may be performed. | |||||
CVE-2018-8779 | 3 Canonical, Debian, Ruby-lang | 3 Ubuntu Linux, Debian Linux, Ruby | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, the UNIXServer.open and UNIXSocket.open methods are not checked for null characters. It may be connected to an unintended socket. | |||||
CVE-2018-8778 | 4 Canonical, Debian, Redhat and 1 more | 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an attacker controlling the unpacking format (similar to format string vulnerabilities) can trigger a buffer under-read in the String#unpack method, resulting in a massive and controlled information disclosure. | |||||
CVE-2018-8777 | 4 Canonical, Debian, Redhat and 1 more | 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an attacker can pass a large HTTP request with a crafted header to WEBrick server or a crafted body to WEBrick server/handler and cause a denial of service (memory consumption). | |||||
CVE-2018-6914 | 4 Canonical, Debian, Redhat and 1 more | 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
Directory traversal vulnerability in the Dir.mktmpdir method in the tmpdir library in Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1 might allow attackers to create arbitrary directories or files via a .. (dot dot) in the prefix argument. | |||||
CVE-2018-16396 | 4 Canonical, Debian, Redhat and 1 more | 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more | 2024-11-21 | 6.8 MEDIUM | 8.1 HIGH |
An issue was discovered in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. It does not taint strings that result from unpacking tainted strings with some formats. | |||||
CVE-2018-16395 | 4 Canonical, Debian, Redhat and 1 more | 5 Ubuntu Linux, Debian Linux, Enterprise Linux and 2 more | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leveraged to create an illegitimate certificate that may be accepted as legitimate and then used in signing or encryption operations. | |||||
CVE-2017-17742 | 2 Debian, Ruby-lang | 2 Debian Linux, Ruby | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1 allows an HTTP Response Splitting attack. An attacker can inject a crafted key and value into an HTTP response for the HTTP server of WEBrick. | |||||
CVE-2016-2338 | 2 Debian, Ruby-lang | 2 Debian Linux, Ruby | 2024-11-21 | N/A | 9.8 CRITICAL |
An exploitable heap overflow vulnerability exists in the Psych::Emitter start_document function of Ruby. In Psych::Emitter start_document function heap buffer "head" allocation is made based on tags array length. Specially constructed object passed as element of tags array can increase this array size after mentioned allocation and cause heap overflow. | |||||
CVE-2015-1855 | 3 Debian, Puppet, Ruby-lang | 5 Debian Linux, Puppet Agent, Puppet Enterprise and 2 more | 2024-11-21 | 4.3 MEDIUM | 5.9 MEDIUM |
verify_certificate_identity in the OpenSSL extension in Ruby before 2.0.0 patchlevel 645, 2.1.x before 2.1.6, and 2.2.x before 2.2.2 does not properly validate hostnames, which allows remote attackers to spoof servers via vectors related to (1) multiple wildcards, (1) wildcards in IDNA names, (3) case sensitivity, and (4) non-ASCII characters. | |||||
CVE-2013-1945 | 1 Ruby-lang | 1 Ruby193 | 2024-11-21 | 2.1 LOW | 3.3 LOW |
ruby193 uses an insecure LD_LIBRARY_PATH setting. | |||||
CVE-2011-4121 | 1 Ruby-lang | 1 Ruby | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
The OpenSSL extension of Ruby (Git trunk) versions after 2011-09-01 up to 2011-11-03 always generated an exponent value of '1' to be used for private RSA key generation. A remote attacker could use this flaw to bypass or corrupt integrity of services, depending on strong private RSA keys generation mechanism. | |||||
CVE-2011-3624 | 1 Ruby-lang | 1 Ruby | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
Various methods in WEBrick::HTTPRequest in Ruby 1.9.2 and 1.8.7 and earlier do not validate the X-Forwarded-For, X-Forwarded-Host and X-Forwarded-Server headers in requests, which might allow remote attackers to inject arbitrary text into log files or bypass intended address parsing via a crafted header. |
