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...

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: 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: 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: 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...
