| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2013-04-03 | CVE-2013-1911 | Improper Input Validation vulnerability in Mark Burns Ldoce 0.0.2 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. | 6.8 |
| 2013-03-01 | CVE-2013-0256 | Cross-site Scripting vulnerability in multiple products 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. | 4.3 |
| 2012-11-28 | CVE-2012-5371 | Cryptographic Issues vulnerability in Ruby-Lang Ruby 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. | 5.0 |
| 2012-11-24 | CVE-2012-4522 | Permissions, Privileges, and Access Controls vulnerability in Ruby-Lang Ruby 1.9.3/2.0.0 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. | 5.0 |
| 2011-08-05 | CVE-2011-3009 | Cryptographic Issues vulnerability in Ruby-Lang Ruby 1.8.6 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. | 5.0 |
| 2011-08-05 | CVE-2011-2705 | Improper Input Validation vulnerability in Ruby-Lang Ruby The SecureRandom.random_bytes 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 earlier process with the same PID. | 5.0 |
| 2011-03-23 | CVE-2011-0188 | Numeric Errors vulnerability in Ruby-Lang Ruby 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." Per: http://lists.apple.com/archives/security-announce/2011/Mar/msg00006.html 'This issue only affects 64-bit Ruby processes'. | 6.8 |
| 2011-03-02 | CVE-2011-1005 | Permissions, Privileges, and Access Controls vulnerability in Ruby-Lang Ruby 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. | 5.0 |
| 2011-03-02 | CVE-2011-1004 | Link Following vulnerability in Ruby-Lang Ruby The FileUtils.remove_entry_secure method in Ruby 1.8.6 through 1.8.6-420, 1.8.7 through 1.8.7-330, 1.8.8dev, 1.9.1 through 1.9.1-430, 1.9.2 through 1.9.2-136, and 1.9.3dev allows local users to delete arbitrary files via a symlink attack. | 6.3 |
| 2009-06-11 | CVE-2009-1904 | Numeric Errors vulnerability in Ruby-Lang Ruby 1.8.6/1.8.7 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. | 5.0 |
