|---|---|---|---|---|---|
| CVE-2015-4020 | 2 Oracle, Rubygems | 2 Solaris, Rubygems | 2023-12-10 | 4.3 MEDIUM | N/A |
| RubyGems 2.0.x before 2.0.17, 2.2.x before 2.2.5, and 2.4.x before 2.4.8 does not validate the hostname when fetching gems or making API requests, which allows remote attackers to redirect requests to arbitrary domains via a crafted DNS SRV record with a domain that is suffixed with the original domain name, aka a "DNS hijack attack." NOTE: this vulnerability exists because to an incomplete fix for CVE-2015-3900. | |||||
| CVE-2012-2126 | 3 Canonical, Redhat, Rubygems | 3 Ubuntu Linux, Openshift, Rubygems | 2023-12-10 | 4.3 MEDIUM | N/A |
| RubyGems before 1.8.23 does not verify an SSL certificate, which allows remote attackers to modify a gem during installation via a man-in-the-middle attack. | |||||
| CVE-2013-4363 | 2 Ruby-lang, Rubygems | 2 Ruby, Rubygems | 2023-12-10 | 4.3 MEDIUM | N/A |
| Algorithmic complexity vulnerability in Gem::Version::ANCHORED_VERSION_PATTERN in lib/rubygems/version.rb in RubyGems before 1.8.23.2, 1.8.24 through 1.8.26, 2.0.x before 2.0.10, and 2.1.x before 2.1.5, 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. NOTE: this issue is due to an incomplete fix for CVE-2013-4287. | |||||
| CVE-2012-2125 | 3 Canonical, Redhat, Rubygems | 3 Ubuntu Linux, Openshift, Rubygems | 2023-12-10 | 5.8 MEDIUM | N/A |
| RubyGems before 1.8.23 can redirect HTTPS connections to HTTP, which makes it easier for remote attackers to observe or modify a gem during installation via a man-in-the-middle attack. | |||||
| CVE-2013-4287 | 3 Redhat, Ruby-lang, Rubygems | 3 Enterprise Linux, Ruby, Rubygems | 2023-12-10 | 4.3 MEDIUM | N/A |
