{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/70487?format=json","vulnerability_id":"VCID-2cnf-zyh4-cuex","summary":"GoBGP is an open source Border Gateway Protocol (BGP) implementation in the Go Programming Language. In version 4.4.0, an unauthenticated remote BGP peer can trigger a fatal panic in GoBGP by sending a specially crafted BGP UPDATE message. When the server receives a message with inconsistent attribute lengths, it improperly handles the internal state transition to a \"withdraw\" action, leading to a nil pointer dereference in the AdjRib.Update function. This causes the entire GoBGP process to crash, resulting in a complete loss of service availability. This issue has been patched in version 4.5.0.","aliases":[{"alias":"CVE-2026-42285"},{"alias":"GHSA-p3w2-64xm-833j"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/43805?format=json","purl":"pkg:deb/debian/gobgp@0?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/gobgp@0%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/43799?format=json","purl":"pkg:deb/debian/gobgp@2.25.0-2?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1cs3-k74w-kygg"},{"vulnerability":"VCID-1eqn-8akp-k3c5"},{"vulnerability":"VCID-42da-ds2p-23ce"},{"vulnerability":"VCID-5jty-ypkz-sqag"},{"vulnerability":"VCID-6x8j-xcy5-suh4"},{"vulnerability":"VCID-8mzj-45bc-47a7"},{"vulnerability":"VCID-a46x-umu5-fybq"},{"vulnerability":"VCID-b759-xchn-5qf5"},{"vulnerability":"VCID-c8za-h2xs-eqhs"},{"vulnerability":"VCID-cxbw-zm2u-5bbe"},{"vulnerability":"VCID-ha64-6fyw-nuag"},{"vulnerability":"VCID-k7du-sx9c-6ff7"},{"vulnerability":"VCID-u8e1-cw3d-nubf"},{"vulnerability":"VCID-v1de-mjt7-kbfh"},{"vulnerability":"VCID-yxkx-wf6f-b3hj"},{"vulnerability":"VCID-yzby-pf8a-gqhs"},{"vulnerability":"VCID-yznm-d9m5-9uf9"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/gobgp@2.25.0-2%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/43800?format=json","purl":"pkg:deb/debian/gobgp@3.10.0-1?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1cs3-k74w-kygg"},{"vulnerability":"VCID-1eqn-8akp-k3c5"},{"vulnerability":"VCID-42da-ds2p-23ce"},{"vulnerability":"VCID-5jty-ypkz-sqag"},{"vulnerability":"VCID-6x8j-xcy5-suh4"},{"vulnerability":"VCID-8mzj-45bc-47a7"},{"vulnerability":"VCID-a46x-umu5-fybq"},{"vulnerability":"VCID-b759-xchn-5qf5"},{"vulnerability":"VCID-c8za-h2xs-eqhs"},{"vulnerability":"VCID-cxbw-zm2u-5bbe"},{"vulnerability":"VCID-ha64-6fyw-nuag"},{"vulnerability":"VCID-k7du-sx9c-6ff7"},{"vulnerability":"VCID-qf45-39ad-uqh6"},{"vulnerability":"VCID-u8e1-cw3d-nubf"},{"vulnerability":"VCID-v1de-mjt7-kbfh"},{"vulnerability":"VCID-yxkx-wf6f-b3hj"},{"vulnerability":"VCID-yzby-pf8a-gqhs"},{"vulnerability":"VCID-yznm-d9m5-9uf9"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/gobgp@3.10.0-1%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/43801?format=json","purl":"pkg:deb/debian/gobgp@3.36.0-2?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1eqn-8akp-k3c5"},{"vulnerability":"VCID-42da-ds2p-23ce"},{"vulnerability":"VCID-5jty-ypkz-sqag"},{"vulnerability":"VCID-6x8j-xcy5-suh4"},{"vulnerability":"VCID-a46x-umu5-fybq"},{"vulnerability":"VCID-b759-xchn-5qf5"},{"vulnerability":"VCID-c8za-h2xs-eqhs"},{"vulnerability":"VCID-ha64-6fyw-nuag"},{"vulnerability":"VCID-k7du-sx9c-6ff7"},{"vulnerability":"VCID-u8e1-cw3d-nubf"},{"vulnerability":"VCID-v1de-mjt7-kbfh"},{"vulnerability":"VCID-yxkx-wf6f-b3hj"},{"vulnerability":"VCID-yzby-pf8a-gqhs"},{"vulnerability":"VCID-yznm-d9m5-9uf9"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/gobgp@3.36.0-2%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/43807?format=json","purl":"pkg:deb/debian/gobgp@4.5.0-1?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/gobgp@4.5.0-1%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/43802?format=json","purl":"pkg:deb/debian/gobgp@4.6.0-1?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/gobgp@4.6.0-1%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/375712?format=json","purl":"pkg:golang/github.com/osrg/gobgp/v4@4.5.0","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:golang/github.com/osrg/gobgp/v4@4.5.0"}],"affected_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/373573?format=json","purl":"pkg:golang/github.com/osrg/gobgp/v4@4.4.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-2cnf-zyh4-cuex"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:golang/github.com/osrg/gobgp/v4@4.4.0"}],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-42285","reference_id":"","reference_type":"","scores":[{"value":"0.00193","scoring_system":"epss","scoring_elements":"0.41252","published_at":"2026-06-12T12:55:00Z"},{"value":"0.00193","scoring_system":"epss","scoring_elements":"0.41263","published_at":"2026-06-14T12:55:00Z"},{"value":"0.00193","scoring_system":"epss","scoring_elements":"0.41086","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00193","scoring_system":"epss","scoring_elements":"0.41272","published_at":"2026-06-13T12:55:00Z"}],"url":"https://api.first.org/data/v1/eps
