Attackers can craft a malicious rules table entry with an oversized rule type value that is used without bounds checking as an index into an internal output-link table, resulting in an out-of-bounds write.","epss":{"date":"2026-11-08","percentile":0.57497,"score":0.0082},"exploits":[{"kind":"exploit","source":"CNA: VulnCheck","url":"https://mehmetince.net/part-1-6-systemic-risks-in-the-managed-postgresql-industry-extension-risks-are-real-exploiting-postgis-memory-corruption-bug-at-neondb-supabase-and-many-more/"}],"kev":null,"metrics":[{"score":8.7,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":8.8,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1794146925628,"publishedAt":1786635374564,"references":[{"source":"CNA: VulnCheck","tags":["technical-description","exploit"],"url":"https://mehmetince.net/part-1-6-systemic-risks-in-the-managed-postgresql-industry-extension-risks-are-real-exploiting-postgis-memory-corruption-bug-at-neondb-supabase-and-many-more/"},{"source":"CNA: VulnCheck","tags":["issue-tracking","patch"],"url":"https://github.com/postgis/address_standardizer/pull/3"},{"source":"CNA: VulnCheck","tags":["issue-tracking","patch"],"url":"https://github.com/postgis/address_standardizer/pull/4"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/postgis/address_standardizer/commit/423570b0dbf6cd9f6fc36de28a636e7b6e9aa8aa"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/postgis-address-standardizer-out-of-bounds-write-via-standardize-address"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
