VCID-f7x5-hz5f-hyd3
Aliases: CVE-2019-8325 GHSA-4wm8-fjv7-j774 |
Improper Restriction of Operations within the Bounds of a Memory Buffer An issue was discovered in RubyGems. Since `Gem::CommandManager#run` calls alert_error without escaping, escape sequence injection is possible. (There are many ways to cause an error.) |
Affected by 6 other vulnerabilities. Affected by 6 other vulnerabilities. Affected by 0 other vulnerabilities. |

VCID-ha3g-uyse-wybx
Aliases: CVE-2019-8322 GHSA-mh37-8c3g-3fgc |
Injection Vulnerability An issue was discovered in RubyGems. The gem owner command outputs the contents of the API response directly to stdout. Therefore, if the response is crafted, escape sequence injection may occur. |
Affected by 6 other vulnerabilities. Affected by 6 other vulnerabilities. Affected by 0 other vulnerabilities. |

VCID-jkwe-c323-3yez
Aliases: CVE-2019-8321 GHSA-fr32-gr5c-xq5c |
Argument Injection or Modification An issue was discovered in RubyGems. Since `Gem::UserInteraction#verbose` calls say without escaping, escape sequence injection is possible. |
Affected by 6 other vulnerabilities. Affected by 6 other vulnerabilities. Affected by 0 other vulnerabilities. |

VCID-ky5r-bch5-m7dv
Aliases: CVE-2019-8323 GHSA-3h4r-pjv6-cph9 |
Injection Vulnerability An issue was discovered in RubyGems. `Gem::GemcutterUtilities#with_response` may output the API response to stdout as it is. Therefore, if the API side modifies the response, escape sequence injection may occur. |
Affected by 6 other vulnerabilities. Affected by 6 other vulnerabilities. Affected by 0 other vulnerabilities. |

VCID-t78a-dw4s-vqf5
Aliases: CVE-2019-8320 GHSA-5x32-c9mf-49cc |
Path Traversal A Directory Traversal issue was discovered in RubyGems. Before making new directories or touching files (which now include path-checking code for symlinks), it would delete the target destination. If that destination was hidden behind a symlink, a malicious gem could delete arbitrary files on the user's machine, presuming the attacker could guess at paths. Given how frequently gem is run as sudo, and how predictable paths are on modern systems (`/tmp`, `/usr`, etc.), this could likely lead to data loss or an unusable system. |

VCID-xgmc-a5rk-zqag
Aliases: CVE-2019-8324 GHSA-76wm-422q-92mq |
Improper Input Validation A crafted gem with a multi-line name is not handled correctly. Therefore, an attacker could inject arbitrary code to the stub line of gemspec, which is evaluated by `ensure_loadable_spec` during the pre-installation check. |
Affected by 6 other vulnerabilities. Affected by 6 other vulnerabilities. Affected by 0 other vulnerabilities. |

CVE-2018-1000075
GHSA-74pv-v9gh-h25p |
| VCID-8hm4-c4w4-gfen | Cross-site Scripting RubyGems contains a Cross Site Scripting (XSS) vulnerability in gem server display of homepage attribute that can result in XSS. This attack appears to be exploitable by the victim browsing to a malicious gem on a vulnerable gem server. |
CVE-2018-1000078
GHSA-87qx-g5wg-mwmj |
| VCID-9t45-d5mf-3uar | Path Traversal RubyGems contains a Directory Traversal vulnerability in gem installation that can result in the gem being able to write to arbitrary filesystem locations during installation. This attack appears to be exploitable by a victim installing a malicious gem. |
CVE-2018-1000079
GHSA-8qxg-mff5-j3wc |
| VCID-af1f-xwwy-jfa8 | RubyGems contains a Deserialization of Untrusted Data vulnerability in owner command that can result in code execution. This attack appears to be exploitable when the victim runs the `gem owner` command on a gem with a specially crafted YAML file. |
CVE-2018-1000074
GHSA-qj2w-mw2r-pv39 |
| VCID-mamm-cvdr-subf | RubyGems contains an Improper Input Validation vulnerability in ruby gems specification homepage attribute that can result in a malicious gem being able to set an invalid homepage URL. |
CVE-2018-1000077
GHSA-gv86-43rv-79m2 |
| VCID-tq93-h2ag-s3bx | Path Traversal RubyGems contains a Directory Traversal vulnerability in install_location function of `package.rb` that can result in path traversal when writing to a symlinked basedir outside the root. |
CVE-2018-1000073
GHSA-gx69-6cp4-hxrj |
| VCID-w4ns-f42m-pyec | RubyGems contains an Improper Verification of Cryptographic Signature vulnerability in `package.rb` that can result in a mis-signed gem being installed, as the tarball would contain multiple gem signatures. |
CVE-2018-1000076
