CVE-2008-3655 1 Ruby-lang 1 Ruby 2025-04-09 7.5 HIGH N/A
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) untrace_var, (2) $PROGRAM_NAME, and (3) syslog at safe level 4, and (4) insecure methods at safe levels 1 through 3.
CVE-2008-2664 3 Canonical, Debian, Ruby-lang 3 Ubuntu Linux, Debian Linux, Ruby 2025-04-09 7.8 HIGH N/A
The rb_str_format 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 allows context-dependent attackers to trigger memory corruption via unspecified vectors related to alloca, a different issue than CVE-2008-2662, CVE-2008-2663, and CVE-2008-2725. NOTE: as of 20080624, there has been inconsistent usage of multiple CVE identifiers related to Ruby. The CVE description should be regarded as authoritative, although it is likely to change.
CVE-2008-2725 3 Canonical, Debian, Ruby-lang 3 Ubuntu Linux, Debian Linux, Ruby 2025-04-09 7.8 HIGH N/A
Integer overflow in the (1) rb_ary_splice 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 rb_ary_replace function in 1.6.x allows context-dependent attackers to trigger memory corruption via unspecified vectors, aka the "REALLOC_N" variant, a different issue than CVE-2008-2662, CVE-2008-2663, and CVE-2008-2664. NOTE: as of 20080624, there has been inconsistent usage of multiple CVE identifiers related to Ruby. The CVE description should be regarded as authoritative, although it is likely to change.
CVE-2008-3657 1 Ruby-lang 1 Ruby 2025-04-09 7.5 HIGH N/A
The dl module in 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 check "taintness" of inputs, which allows context-dependent attackers to bypass safe levels and execute dangerous functions by accessing a library using DL.dlopen.
CVE-2009-4124 1 Ruby-lang 1 Ruby 2025-04-09 10.0 HIGH N/A
Heap-based buffer overflow in the rb_str_justify function in string.c in Ruby 1.9.1 before 1.9.1-p376 allows context-dependent attackers to execute arbitrary code via unspecified vectors involving (1) String#ljust, (2) String#center, or (3) String#rjust. NOTE: some of these details are obtained from third party information.
CVE-2009-0642 1 Ruby-lang 1 Ruby 2025-04-09 6.8 MEDIUM N/A
ext/openssl/ossl_ocsp.c in Ruby 1.8 and 1.9 does not properly check the return value from the OCSP_basic_verify function, which might allow remote attackers to successfully present an invalid X.509 certificate, possibly involving a revoked certificate.
CVE-2008-3905 1 Ruby-lang 1 Ruby 2025-04-09 5.8 MEDIUM N/A
resolv.rb in Ruby 1.8.5 and earlier, 1.8.6 before 1.8.6-p287, 1.8.7 before 1.8.7-p72, and 1.9 r18423 and earlier uses sequential transaction IDs and constant source ports for DNS requests, which makes it easier for remote attackers to spoof DNS responses, a different vulnerability than CVE-2008-1447.
CVE-2008-3443 1 Ruby-lang 1 Ruby 2025-04-09 5.0 MEDIUM N/A
The regular expression engine (regex.c) in 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 allows remote attackers to cause a denial of service (infinite loop and crash) via multiple long requests to a Ruby socket, related to memory allocation failure, and as demonstrated against Webrick.
CVE-2008-2726 3 Canonical, Debian, Ruby-lang 3 Ubuntu Linux, Debian Linux, Ruby 2025-04-09 7.8 HIGH N/A
Integer overflow in the (1) rb_ary_splice 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 rb_ary_replace function in 1.6.x allows context-dependent attackers to trigger memory corruption, aka the "beg + rlen" issue. NOTE: as of 20080624, there has been inconsistent usage of multiple CVE identifiers related to Ruby. The CVE description should be regarded as authoritative, although it is likely to change.
CVE-2008-4310 1 Ruby-lang 1 Ruby 2025-04-09 7.8 HIGH N/A
httputils.rb in WEBrick in Ruby 1.8.1 and 1.8.5, as used in Red Hat Enterprise Linux 4 and 5, allows remote attackers to cause a denial of service (CPU consumption) via a crafted HTTP request. NOTE: this issue exists because of an incomplete fix for CVE-2008-3656.
CVE-2008-3656 1 Ruby-lang 1 Ruby 2025-04-09 7.8 HIGH N/A
Algorithmic complexity vulnerability in the WEBrick::HTTPUtils.split_header_value function in WEBrick::HTTP::DefaultFileHandler in WEBrick in 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 allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted HTTP request that is processed by a backtracking regular expression.
CVE-2008-3790 1 Ruby-lang 1 Ruby 2025-04-09 5.0 MEDIUM N/A
The REXML module in Ruby 1.8.6 through 1.8.6-p287, 1.8.7 through 1.8.7-p72, and 1.9 allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML document with recursively nested entities, aka an "XML entity explosion."
CVE-2009-4492 1 Ruby-lang 2 Ruby, Webrick 2025-04-09 7.5 HIGH N/A
WEBrick 1.3.1 in Ruby 1.8.6 through patchlevel 383, 1.8.7 through patchlevel 248, 1.8.8dev, 1.9.1 through patchlevel 376, and 1.9.2dev writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator.
CVE-2009-1904 1 Ruby-lang 1 Ruby 2025-04-09 5.0 MEDIUM N/A
The BigDecimal library in Ruby 1.8.6 before p369 and 1.8.7 before p173 allows context-dependent attackers to cause a denial of service (application crash) via a string argument that represents a large number, as demonstrated by an attempted conversion to the Float data type.
CVE-2008-2376 2 Redhat, Ruby-lang 2 Fedora 8, Ruby 2025-04-09 7.5 HIGH N/A
Integer overflow in the rb_ary_fill function in array.c in Ruby before revision 17756 allows context-dependent attackers to cause a denial of service (crash) or possibly have unspecified other impact via a call to the Array#fill method with a start (aka beg) argument greater than ARY_MAX_SIZE. NOTE: this issue exists because of an incomplete fix for other closely related integer overflows.
CVE-2024-49761 2 Netapp, Ruby-lang 3 Ontap Tools, Rexml, Ruby 2025-03-21 N/A 7.5 HIGH
REXML is an XML toolkit for Ruby. The REXML gem before 3.3.9 has a ReDoS vulnerability when it parses an XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;). This does not happen with Ruby 3.2 or later. Ruby 3.1 is the only affected maintained Ruby. The REXML gem 3.3.9 or later include the patch to fix the vulnerability.
CVE-2024-26142 2 Ruby-lang, Rubyonrails 2 Ruby, Rails 2025-02-14 N/A 7.5 HIGH
Rails is a web-application framework. Starting in version 7.1.0, there is a possible ReDoS vulnerability in the Accept header parsing routines of Action Dispatch. This vulnerability is patched in 7.1.3.1. Ruby 3.2 has mitigations for this problem, so Rails applications using Ruby 3.2 or newer are unaffected.
CVE-2023-28756 3 Debian, Fedoraproject, Ruby-lang 4 Debian Linux, Fedora, Ruby and 1 more 2024-11-21 N/A 5.3 MEDIUM
A ReDoS issue was discovered in the Time component through 0.2.1 in Ruby through 3.2.1. The Time parser mishandles invalid URLs that have specific characters. It causes an increase in execution time for parsing strings to Time objects. The fixed versions are 0.1.1 and 0.2.2.
CVE-2023-22795 3 Debian, Ruby-lang, Rubyonrails 3 Debian Linux, Ruby, Rails 2024-11-21 N/A 7.5 HIGH
A regular expression based DoS vulnerability in Action Dispatch <6.1.7.1 and <7.0.4.1 related to the If-None-Match header. A specially crafted HTTP If-None-Match header can cause the regular expression engine to enter a state of catastrophic backtracking, when on a version of Ruby below 3.2.0. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability All users running an affected release should either upgrade or use one of the workarounds immediately.
CVE-2022-28739 3 Apple, Debian, Ruby-lang 3 Macos, Debian Linux, Ruby 2024-11-21 4.3 MEDIUM 7.5 HIGH
There is a buffer over-read in Ruby before 2.6.10, 2.7.x before 2.7.6, 3.x before 3.0.4, and 3.1.x before 3.1.2. It occurs in String-to-Float conversion, including Kernel#Float and String#to_f.
