Vulnerability	Summary	Fixed by
VCID-4qeb-7mva-aaak Aliases: CVE-2021-32066	An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. Net::IMAP does not raise an exception when StartTLS fails with an an unknown response, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack."	2.5.1-1ubuntu1.10 Affected by 0 other vulnerabilities.
VCID-6u9x-t53x-aaak Aliases: CVE-2018-16395 GHSA-mmrq-6999-72v8	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.	2.5.1-6ubuntu3 Affected by 11 other vulnerabilities.

VCID-haxq-y43b-aaah Aliases: CVE-2019-8325 GHSA-4wm8-fjv7-j774	An issue was discovered in RubyGems 2.6 and later through 3.0.2. Since Gem::CommandManager#run calls alert_error without escaping, escape sequence injection is possible. (There are many ways to cause an error.)	2.5.5-1ubuntu1 Affected by 5 other vulnerabilities. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }}
VCID-jfww-25z5-aaab Aliases: CVE-2019-16255	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.	2.5.5-4ubuntu2.1 Affected by 0 other vulnerabilities.
VCID-kz8n-gkrg-aaad Aliases: CVE-2019-16201	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.	2.5.5-4ubuntu2.1 Affected by 0 other vulnerabilities.
VCID-mjme-uddr-aaag Aliases: CVE-2019-15845	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.	2.5.5-4ubuntu2.1 Affected by 0 other vulnerabilities.
VCID-nw56-rqyq-aaaq Aliases: CVE-2021-28965 GHSA-8cr8-4vfw-mr7h	The REXML gem before 3.2.5 in Ruby before 2.6.7, 2.7.x before 2.7.3, and 3.x before 3.0.1 does not properly address XML round-trip issues. An incorrect document can be produced after parsing and serializing.	2.5.1-1ubuntu1.9 Affected by 3 other vulnerabilities. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }}
VCID-pguq-6u98-aaae Aliases: CVE-2019-8322 GHSA-mh37-8c3g-3fgc	An issue was discovered in RubyGems 2.6 and later through 3.0.2. The gem owner command outputs the contents of the API response directly to stdout. Therefore, if the response is crafted, escape sequence injection may occur.	2.5.5-1ubuntu1 Affected by 5 other vulnerabilities. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }}
VCID-qrfr-32tv-aaas Aliases: CVE-2019-16254	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.	2.5.5-4ubuntu2.1 Affected by 0 other vulnerabilities.
VCID-rzw4-4w1h-aaaj Aliases: CVE-2020-10933	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.	2.5.1-1ubuntu1.8 Affected by 4 other vulnerabilities. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }}
VCID-smb4-9ksp-aaah Aliases: CVE-2019-8323 GHSA-3h4r-pjv6-cph9	An issue was discovered in RubyGems 2.6 and later through 3.0.2. Gem::GemcutterUtilities#with_response may output the API response to stdout as it is. Therefore, if the API side modifies the response, escape sequence injection may occur.	2.5.5-1ubuntu1 Affected by 5 other vulnerabilities. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }}
VCID-sth6-4edt-aaar Aliases: CVE-2020-25613 GHSA-gwfg-cqmg-cf8f	An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack.	2.5.1-1ubuntu1.8 Affected by 4 other vulnerabilities. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }}
VCID-t5p8-75v9-aaap Aliases: CVE-2020-10663 GHSA-jphg-qwrw-7w9g	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.	2.5.1-1ubuntu1.8 Affected by 4 other vulnerabilities. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }}
VCID-wbaq-bqk9-aaas Aliases: CVE-2019-8320 GHSA-5x32-c9mf-49cc	A Directory Traversal issue was discovered in RubyGems 2.7.6 and later through 3.0.2. Before making new directories or touching files (which now include path-checking code for symlinks), it would delete the target destination. If that destination was hidden behind a symlink, a malicious gem could delete arbitrary files on the user's machine, presuming the attacker could guess at paths. Given how frequently gem is run as sudo, and how predictable paths are on modern systems (/tmp, /usr, etc.), this could likely lead to data loss or an unusable system.	2.5.5-1ubuntu1 Affected by 5 other vulnerabilities. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }}
VCID-xv5b-y3av-aaae Aliases: CVE-2021-31810	An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. A malicious FTP server can use the PASV response to trick Net::FTP into connecting back to a given IP address and port. This potentially makes curl extract information about services that are otherwise private and not disclosed (e.g., the attacker can conduct port scans and service banner extractions).	2.5.1-1ubuntu1.10 Affected by 0 other vulnerabilities.
