CVE-2011-2686 1 Ruby-lang 1 Ruby 2025-04-11 5.0 MEDIUM 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.

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-2013-4287 3 Redhat, Ruby-lang, Rubygems 3 Enterprise Linux, Ruby, Rubygems 2025-04-11 4.3 MEDIUM N/A
Algorithmic complexity vulnerability in Gem::Version::VERSION_PATTERN in lib/rubygems/version.rb in RubyGems before 1.8.23.1, 1.8.24 through 1.8.25, 2.0.x before 2.0.8, and 2.1.x before 2.1.0, as used in Ruby 1.9.0 through 2.0.0p247, allows remote attackers to cause a denial of service (CPU consumption) via a crafted gem version that triggers a large amount of backtracking in a regular expression.
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-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-2013-2065 2 Opensuse, Ruby-lang 2 Opensuse, Ruby 2025-04-11 6.4 MEDIUM N/A
(1) DL and (2) Fiddle in Ruby 1.9 before 1.9.3 patchlevel 426, and 2.0 before 2.0.0 patchlevel 195, do not perform taint checking for native functions, which allows context-dependent attackers to bypass intended $SAFE level restrictions.
CVE-2010-2489 2 Microsoft, Ruby-lang 2 Windows, Ruby 2025-04-11 7.2 HIGH N/A
Buffer overflow in Ruby 1.9.x before 1.9.1-p429 on Windows might allow local users to gain privileges via a crafted ARGF.inplace_mode value that is not properly handled when constructing the filenames of the backup files.
CVE-2013-1655 3 Puppet, Puppetlabs, Ruby-lang 4 Puppet, Puppet Enterprise, Puppet and 1 more 2025-04-11 7.5 HIGH N/A
Puppet 2.7.x before 2.7.21 and 3.1.x before 3.1.1, when running Ruby 1.9.3 or later, allows remote attackers to execute arbitrary code via vectors related to "serialized attributes."
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-2008-2664 3 Canonical, Debian, Ruby-lang 3 Ubuntu Linux, Debian Linux, Ruby 2025-04-09 7.8 HIGH N/A
