{"id":"GHSA-8fcj-gf77-47mg","summary":"Denial of service (DoS) when processing Git credentials","details":"### Impact\n\nA denial of services (DoS) vulnerability was discovered in Wrangler Git package affecting versions up to and including `v1.0.0`.\n\nSpecially crafted Git credentials can result in a denial of service (DoS) attack on an application that uses Wrangler due to the exhaustion of the available memory and CPU resources. This is caused by a lack of input validation of Git credentials before they are used, which may lead to a denial of service in some cases. This issue can be triggered when accessing both private and public Git repositories. \n\n### Workarounds\n\nA workaround is to sanitize input passed to the Git package to remove potential unsafe and ambiguous characters. Otherwise, the best course of action is to update to a patched Wrangler version.\n\n### Patches\n\nPatched versions include `v1.0.1` and later and the backported tags - `v0.7.4-security1`, `v0.8.5-security1` and `v0.8.11`.\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Reach out to [SUSE Rancher Security team](https://github.com/rancher/rancher/security/policy) for security related inquiries.\n* Open an issue in [Rancher](https://github.com/rancher/rancher/issues/new/choose) or [Wrangler](https://github.com/rancher/wrangler/issues/new) repository.\n* Verify our [support matrix](https://www.suse.com/suse-rancher/support-matrix/all-supported-versions/) and [product support lifecycle](https://www.suse.com/lifecycle/).","aliases":["CVE-2022-43756","GO-2023-1515"],"modified":"2023-11-08T04:10:46.341625Z","published":"2023-01-25T19:40:26Z","database_specific":{"cwe_ids":["CWE-150","CWE-74"],"github_reviewed_at":"2023-01-25T19:40:26Z","github_reviewed":true,"nvd_published_at":"2023-02-07T13:15:00Z","severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/rancher/wrangler/security/advisories/GHSA-8fcj-gf77-47mg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-43756"},{"type":"WEB","url":"https://github.com/rancher/wrangler/commit/341018c8fef3e12867c7cb2649bd2cecac75f287"},{"type":"WEB","url":"https://bugzilla.suse.com/show_bug.cgi?id=1205296"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-8fcj-gf77-47mg"},{"type":"WEB","url":"https://github.com/rancher/rancher/security/policy"},{"type":"PACKAGE","url":"https://github.com/rancher/wrangler"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2023-1515"}],"affected":[{"package":{"name":"github.com/rancher/wrangler","ecosystem":"Go","purl":"pkg:golang/github.com/rancher/wrangler"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.7.4-security1"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 0.7.3","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/01/GHSA-8fcj-gf77-47mg/GHSA-8fcj-gf77-47mg.json"}},{"package":{"name":"github.com/rancher/wrangler","ecosystem":"Go","purl":"pkg:golang/github.com/rancher/wrangler"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.8.0"},{"fixed":"0.8.5-security1"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 0.8.4","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/01/GHSA-8fcj-gf77-47mg/GHSA-8fcj-gf77-47mg.json"}},{"package":{"name":"github.com/rancher/wrangler","ecosystem":"Go","purl":"pkg:golang/github.com/rancher/wrangler"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.0.0"},{"fixed":"1.0.1"}]}],"versions":["1.0.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/01/GHSA-8fcj-gf77-47mg/GHSA-8fcj-gf77-47mg.json"}},{"package":{"name":"github.com/rancher/wrangler","ecosystem":"Go","purl":"pkg:golang/github.com/rancher/wrangler"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.8.6"},{"fixed":"0.8.11"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/01/GHSA-8fcj-gf77-47mg/GHSA-8fcj-gf77-47mg.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:H"}]}
