rubygem-json: Unsafe object creation vulnerability in JSON

A flaw was found in rubygem-json. While parsing certain JSON documents, the json gem including the one bundled with Ruby can be coerced into creating arbitrary objects in the target system. This is the same issue as CVE-2013-0269...

ruby: Potential HTTP request smuggling in WEBrick

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 po...

ruby: Code injection via command argument of Shell#test / Shell#[]

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 Shelltest in lib/shell.rb is untrusted data. An attacker can exploit this to call an arbitrary Ruby method...

ruby: NUL injection vulnerability of File.fnmatch and File.fnmatch?

A flaw was discovered in Ruby in the way certain functions handled strings containing NULL bytes. Specifically, the built-in methods File.fnmatch and its alias File.fnmatch? did not properly handle path patterns containing the NULL byte. A remote attacker could exploit this flaw to make a Ruby...

ruby: Regular expression denial of service vulnerability of WEBrick's Digest authentication

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...

ruby: HTTP response splitting in WEBrick

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...

ruby: XML round-trip vulnerability in REXML

A flaw was found in the way the Ruby REXML library parsed XML documents. Parsing a specially crafted XML document using REXML and writing parsed data back to a new XML document results in creating a document with a different structure. This issue could affect the integrity of processed data in...

ruby: BasicSocket#read_nonblock method leads to information disclosure

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 BasicSocketreadnonblockrequestedsize, 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 valu...
