{"apiVersion":"1.0","identifier":"CVE-2026-78183","description":"DBD::Pg version 3.21.0 for Perl has a heap out-of-bounds write in quote_float. quote_float() allocates the length of the string + 1, which is the size of the bare numeric symbol plus NULL. But for special literals NaN, Inf, +Inf, -Inf, Infinity, +Infinity, -Infinity it emits the literal surrounded by quotes plus NULL, which is length + 3 bytes. Every recognised literal (case-insensitive) overflows by 2 bytes, a single quote and a NULL. This can be reached by the $dbh->quote method, for example $dbh->quote( -Infinity-, DBI::SQL_NUMERIC ). This regression was introduced in 3.21.0 by the quote.c rewrite.","publishedAt":"2026-08-23T20:16:50","lastModifiedAt":"2026-08-26T16:51:19","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-78183","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.0055,"riskScore":1.03,"affectedProduct":"DBD::Pg","affectedVersions":"==3.21.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-78183","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-78183","en":"https://www.redsauce.net/en/cves/CVE-2026-78183","fr":"https://www.redsauce.net/fr/cves/CVE-2026-78183","pt":"https://www.redsauce.net/pt/cves/CVE-2026-78183","de":"https://www.redsauce.net/de/cves/CVE-2026-78183","sk":"https://www.redsauce.net/sk/cves/CVE-2026-78183","el":"https://www.redsauce.net/el/cves/CVE-2026-78183"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-78183"}}
