{"id":"BIT-gitlab-2021-32823","summary":"Potential Denial-of-Service in bindata","details":"In the bindata RubyGem before version 2.4.10 there is a potential denial-of-service vulnerability. In affected versions it is very slow for certain classes in BinData to be created. For example BinData::Bit100000, BinData::Bit100001, BinData::Bit100002, BinData::Bit\u003cN\u003e. In combination with \u003cuser_input\u003e.constantize there is a potential for a CPU-based DoS. In version 2.4.10 bindata improved the creation time of Bits and Integers.","aliases":["CVE-2021-32823","GHSA-hj56-84jw-67h6"],"modified":"2026-09-08T08:47:37.926024394Z","published":"2024-03-06T11:18:52.964Z","database_specific":{"cpes":["cpe:2.3:a:gitlab:gitlab:*:*:*:*:community:*:*:*","cpe:2.3:a:gitlab:gitlab:*:*:*:*:enterprise:*:*:*"],"severity":"Low"},"references":[{"type":"ADVISORY","url":"https://about.gitlab.com/releases/2021/06/01/security-release-gitlab-13-12-2-released/#update-bindata-dependency"},{"type":"ADVISORY","url":"https://github.com/dmendel/bindata/blob/v2.4.10/ChangeLog.rdoc#version-2410-2021-05-18-"},{"type":"ADVISORY","url":"https://github.com/dmendel/bindata/commit/d99f050b88337559be2cb35906c1f8da49531323"},{"type":"ADVISORY","url":"https://github.com/rubysec/ruby-advisory-db/issues/476"},{"type":"ADVISORY","url":"https://rubygems.org/gems/bindata"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-32823"}],"affected":[{"package":{"name":"gitlab","ecosystem":"Bitnami","purl":"pkg:bitnami/gitlab"},"ranges":[{"type":"SEMVER","events":[{"introduced":"12.0.0"},{"fixed":"13.10.5"},{"introduced":"13.11.0"},{"fixed":"13.11.5"},{"introduced":"13.12.0"},{"fixed":"13.12.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/gitlab/BIT-gitlab-2021-32823.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}],"schema_version":"1.9.0"}
