CVE-2013-5647 2 Adam Zaninovich, Ruby-lang 2 Sounder, Ruby 2025-04-11 7.5 HIGH N/A
lib/sounder/sound.rb in the sounder gem 1.0.1 for Ruby allows remote attackers to execute arbitrary commands via shell metacharacters in a filename.
CVE-2011-1005 1 Ruby-lang 1 Ruby 2025-04-11 5.0 MEDIUM N/A
The safe-level feature in Ruby 1.8.6 through 1.8.6-420, 1.8.7 through 1.8.7-330, and 1.8.8dev allows context-dependent attackers to modify strings via the Exception#to_s method, as demonstrated by changing an intended pathname.
CVE-2013-2119 3 Phusion, Redhat, Ruby-lang 3 Passenger, Openshift, Ruby 2025-04-11 4.6 MEDIUM N/A
Phusion Passenger gem before 3.0.21 and 4.0.x before 4.0.5 for Ruby allows local users to cause a denial of service (prevent application start) or gain privileges by pre-creating a temporary "config" file in a directory with a predictable name in /tmp/ before it is used by the gem.
CVE-2013-1821 1 Ruby-lang 1 Ruby 2025-04-11 5.0 MEDIUM N/A
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.
CVE-2012-4481 1 Ruby-lang 1 Ruby 2025-04-11 4.3 MEDIUM N/A
The safe-level feature in Ruby 1.8.7 allows context-dependent attackers to modify strings via the NameError#to_s method when operating on Ruby objects. NOTE: this issue is due to an incomplete fix for CVE-2011-1005.
CVE-2011-0188 2 Apple, Ruby-lang 3 Mac Os X, Mac Os X Server, Ruby 2025-04-11 6.8 MEDIUM N/A
The VpMemAlloc function in bigdecimal.c in the BigDecimal class in Ruby 1.9.2-p136 and earlier, as used on Apple Mac OS X before 10.6.7 and other platforms, does not properly allocate memory, which allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving creation of a large BigDecimal value within a 64-bit process, related to an "integer truncation issue."
CVE-2011-4815 1 Ruby-lang 1 Ruby 2025-04-11 7.8 HIGH N/A
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.
CVE-2013-0233 3 Opensuse, Plataformatec, Ruby-lang 3 Opensuse, Devise, Ruby 2025-04-11 6.8 MEDIUM N/A
Devise gem 2.2.x before 2.2.3, 2.1.x before 2.1.3, 2.0.x before 2.0.5, and 1.5.x before 1.5.4 for Ruby, when using certain databases, does not properly perform type conversion when performing database queries, which might allow remote attackers to cause incorrect results to be returned and bypass security checks via unknown vectors, as demonstrated by resetting passwords of arbitrary accounts.
CVE-2013-1933 2 Documentcloud, Ruby-lang 2 Karteek-docsplit, Ruby 2025-04-11 9.3 HIGH N/A
The extract_from_ocr function in lib/docsplit/text_extractor.rb in the Karteek Docsplit (karteek-docsplit) gem 0.5.4 for Ruby allows context-dependent attackers to execute arbitrary commands via shell metacharacters in a PDF filename.
CVE-2011-3009 1 Ruby-lang 1 Ruby 2025-04-11 5.0 MEDIUM N/A
Ruby before 1.8.6-p114 does not reset the random seed upon forking, which makes it easier for context-dependent attackers to predict the values of random numbers by leveraging knowledge of the number sequence obtained in a different child process, a related issue to CVE-2003-0900.
CVE-2012-4522 1 Ruby-lang 1 Ruby 2025-04-11 5.0 MEDIUM N/A
The rb_get_path_check function in file.c in Ruby 1.9.3 before patchlevel 286 and Ruby 2.0.0 before r37163 allows context-dependent attackers to create files in unexpected locations or with unexpected names via a NUL byte in a file path.
CVE-2013-1948 2 Rob Westgeest, Ruby-lang 2 Md2pdf, Ruby 2025-04-11 10.0 HIGH N/A
converter.rb in the md2pdf gem 0.0.1 for Ruby allows context-dependent attackers to execute arbitrary commands via shell metacharacters in a filename.
CVE-2013-1911 2 Mark Burns, Ruby-lang 2 Ldoce, Ruby 2025-04-11 6.8 MEDIUM N/A
lib/ldoce/word.rb in the ldoce 0.0.2 gem for Ruby allows remote attackers to execute arbitrary commands via shell metacharacters in (1) an mp3 URL or (2) file name.
CVE-2013-0256 2 Canonical, Ruby-lang 3 Ubuntu Linux, Rdoc, Ruby 2025-04-11 4.3 MEDIUM N/A
darkfish.js in RDoc 2.3.0 through 3.12 and 4.x before 4.0.0.preview2.1, as used in Ruby, does not properly generate documents, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted URL.
CVE-2013-4164 1 Ruby-lang 1 Ruby 2025-04-11 6.8 MEDIUM N/A
Heap-based buffer overflow in Ruby 1.8, 1.9 before 1.9.3-p484, 2.0 before 2.0.0-p353, 2.1 before 2.1.0 preview2, and trunk before revision 43780 allows context-dependent attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a string that is converted to a floating point value, as demonstrated using (1) the to_f method or (2) JSON.parse.
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-2008-1891 1 Ruby-lang 1 Ruby 2025-04-09 5.0 MEDIUM N/A
Directory traversal vulnerability in WEBrick 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, when using NTFS or FAT filesystems, allows remote attackers to read arbitrary CGI files via a trailing (1) + (plus), (2) %2b (encoded plus), (3) . (dot), (4) %2e (encoded dot), or (5) %20 (encoded space) character in the URI, possibly related to the WEBrick::HTTPServlet::FileHandler and WEBrick::HTTPServer.new functionality and the :DocumentRoot option.
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-2009-4124 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-2007-5162 1 Ruby-lang 1 Ruby 2025-04-09 4.3 MEDIUM N/A
The connect method in lib/net/http.rb in the (1) Net::HTTP and (2) Net::HTTPS libraries in Ruby 1.8.5 and 1.8.6 does not verify that the commonName (CN) field in a server certificate matches the domain name in an HTTPS request, which makes it easier for remote attackers to intercept SSL transmissions via a man-in-the-middle attack or spoofed web site.
