{"id":"CVE-2022-23525","aliases":["BIT-helm-2022-23525","GHSA-53c4-hhmh-vw5q","GO-2022-1165"],"url":"https://o3.security/vulnerability/CVE-2022-23525","summary":"Helm vulnerable to Denial of service via NULL Pointer Dereference","details":"Fuzz testing, by Ada Logics and sponsored by the CNCF, identified input to functions in the `_repo_` package that can cause a segmentation violation. Applications that use functions from the `_repo_` package in the Helm SDK can have a Denial of Service attack when they use this package and it panics.\n\n### Impact\n\nThe `_repo_` package contains a handler that processes the index file of a repository. For example, the Helm client adds references to chart repositories where charts are managed. The `_repo_` package parses the index file of the repository and loads it into structures Go can work with. Some index files can cause array data structures to be created causing a memory violation.\n\nApplications that use the `_repo_` package in the Helm SDK to parse an index file can suffer a Denial of Service when that input causes a panic that cannot be recovered from.\n\nThe Helm Client will panic with an index file that causes a memory violation panic. Helm is not a long running service so the panic will not affect future uses of the Helm client.\n\n### Patches\n\nThis issue has been resolved in 3.10.3. \n\n### Workarounds\n\nSDK users can validate index files that are correctly formatted before passing them to the `_repo_` functions.\n\n### For more information\n\nHelm's security policy is spelled out in detail in our [SECURITY](https://github.com/helm/community/blob/master/SECURITY.md) document.\n\n### Credits\n\nDisclosed by Ada Logics in a fuzzing audit sponsored by CNCF.","published":"2022-12-15T00:38:09.873Z","modified":"2026-08-12T03:51:29.252019418Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"helm.sh/helm/v3","fixedVersion":"3.10.3"}],"fix":{"url":"https://github.com/helm/helm/commit/638ebffbc2e445156f3978f02fd83d9af1e56f5b","label":"helm/helm@638ebff"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23525.json"},{"type":"ADVISORY","url":"https://github.com/helm/helm/security/advisories/GHSA-53c4-hhmh-vw5q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23525"},{"type":"FIX","url":"https://github.com/helm/helm/commit/638ebffbc2e445156f3978f02fd83d9af1e56f5b"},{"type":"PACKAGE","url":"https://github.com/helm/helm"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2022-1165"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:29.252019418Z"}}
