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: 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: entity expansion DoS vulnerability in REXML
lib/rexml/text.rb in the REXML parser in Ruby before 1.9.3-p392 allows remote attackers to cause a denial of service memory consumption and crash via crafted text nodes in an XML document, aka an XML Entity Expansion XEE attack...
ruby: multiple insufficient safe mode restrictions
Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 does not properly restrict access to critical variables and methods at various safe levels, which allows context-dependent attackers to bypass intended access restrictions via 1 untracevar, 2...
ruby: integer overflow in rb_ary_splice/update/replace() - REALLOC_N
Integer overflow in the 1 rbarysplice function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, and 1.8.7 before 1.8.7-p22; and 2 the rbaryreplace function in 1.6.x allows context-dependent attackers to trigger memory corruption via unspecified vectors, aka the...
Moderate: Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update
An update for Red Hat Hardened Images RPMs is now available. This update includes the following RPMs: ruby4.0: ruby4.0-4.0.0-33.3.hum1 aarch64, x8664 ruby4.0-bundled-gems-4.0.0-33.3.hum1 aarch64, x8664 ruby4.0-default-gems-4.0.0-33.3.hum1 noarch ruby4.0-devel-4.0.0-33.3.hum1 aarch64, x8664...
ruby: FTP PASV command response can cause Net::FTP to connect to arbitrary host
Ruby's Net::FTP module trusted the IP address included in the FTP server's response to the PASV command. A malicious FTP server could use this to make Ruby applications using the Net::FTP module to connect to arbitrary hosts and use this to perform port scanning or information extraction from...
ruby: REXML incomplete fix for CVE-2014-8080
The REXML parser in Ruby 1.9.x before 1.9.3 patchlevel 551, 2.0.x before 2.0.0 patchlevel 598, and 2.1.x before 2.1.5 allows remote attackers to cause a denial of service CPU and memory consumption a crafted XML document containing an empty string in an entity that is used in a large number of...
ruby: REXML billion laughs attack via parameter entity expansion
The REXML parser in Ruby 1.9.x before 1.9.3-p550, 2.0.x before 2.0.0-p594, and 2.1.x before 2.1.4 allows remote attackers to cause a denial of service memory consumption via a crafted XML document, aka an XML Entity Expansion XEE attack...
ruby: hash table collisions CPU usage DoS (oCERT-2011-003)
Ruby aka CRuby before 1.8.7-p357 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service CPU consumption via crafted input to an application that maintains a hash table...
ruby: Buffer overrun in String-to-Float conversion
A buffer overrun vulnerability was found in Ruby. The issue occurs in a conversion algorithm from a String to a Float that causes process termination due to a segmentation fault, but under limited circumstances. This flaw may cause an illegal memory read...
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: off-by-one stack-based buffer overflow in the encodes() function
Off-by-one error in the encodes function in pack.c in Ruby 1.9.3 and earlier, and 2.x through 2.1.2, when using certain format string specifiers, allows context-dependent attackers to cause a denial of service segmentation fault via vectors that trigger a stack-based buffer overflow...
ruby: Properly initialize the random number generator when forking new process
The SecureRandom.randombytes function in lib/securerandom.rb in Ruby before 1.8.7-p352 and 1.9.x before 1.9.2-p290 relies on PID values for initialization, which makes it easier for context-dependent attackers to predict the result string by leveraging knowledge of random strings obtained in an...
ruby: integer overflow in rb_ary_splice/update/replace() - beg + rlen
Integer overflow in the 1 rbarysplice function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2; and 2 the rbaryreplace function in 1.6.x allows context-dependent attackers to trigger memory corruption, aka the "beg +...
ruby: Unsafe parsing of long strings via decode_www_form_component method
The URI.decodewwwformcomponent method in Ruby before 1.9.2-p330 allows remote attackers to cause a denial of service catastrophic regular expression backtracking, resource consumption, or application crash via a crafted string...
ruby: Murmur hash-flooding DoS flaw in ruby 1.9 (oCERT-2012-001)
Ruby aka CRuby 1.9 before 1.9.3-p327 and 2.0 before r37575 computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service CPU consumption via crafted input to an application that maintains...
ruby: Arbitrary memory address read vulnerability with Regex search
A flaw was found in Ruby. If attacker-supplied data is provided to the Ruby regex compiler, it is possible to extract arbitrary heap data relative to the start of the text, including pointers and sensitive strings...
