CVE-2011-2686 1 Ruby-lang 1 Ruby 2025-04-11 N/A
Ruby before 1.8.7-p352 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. NOTE: this issue exists because of a regression during Ruby 1.8.6 development.
CVE-2011-4815 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2025-04-11 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-2012-4522 2 Redhat, Ruby-lang 3 Enterprise Linux, Openshift, Ruby 2025-04-11 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-2012-5371 2 Redhat, Ruby-lang 2 Openshift, Ruby 2025-04-11 N/A
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 a hash table, as demonstrated by a universal multicollision attack against a variant of the MurmurHash2 algorithm, a different vulnerability than CVE-2011-4815.
CVE-2013-1911 2 Mark Burns, Ruby-lang 2 Ldoce, Ruby 2025-04-11 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-2013-5647 2 Adam Zaninovich, Ruby-lang 2 Sounder, Ruby 2025-04-11 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-2012-4464 2 Redhat, Ruby-lang 2 Openshift, Ruby 2025-04-11 N/A
Ruby 1.9.3 before patchlevel 286 and 2.0 before revision r37068 allows context-dependent attackers to bypass safe-level restrictions and modify untainted strings via the (1) exc_to_s or (2) name_err_to_s API function, which marks the string as tainted, a different vulnerability than CVE-2012-4466. NOTE: this issue might exist because of a CVE-2011-1005 regression.
CVE-2012-4481 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2025-04-11 N/A

CVE-2013-1933 2 Documentcloud, Ruby-lang 2 Karteek-docsplit, Ruby 2025-04-11 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-2013-1948 2 Rob Westgeest, Ruby-lang 2 Md2pdf, Ruby 2025-04-11 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-2011-1005 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2025-04-11 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-2013-0256 5 Canonical, Cloudforms Cloudengine, Redhat and 2 more 6 Ubuntu Linux, 1, Openshift and 3 more 2025-04-11 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 2 Redhat, Ruby-lang 6 Cloudforms Managementengine, Enterprise Linux, Openstack and 3 more 2025-04-11 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-2008-3655 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2025-04-09 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-2008-4310 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2025-04-09 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-2009-4492 2 Redhat, Ruby-lang 3 Enterprise Linux, Ruby, Webrick 2025-04-09 N/A
