Summary
postgresql-14, postgresql-16, postgresql-17 vulnerabilities
Details

Altan Birler discovered that PostgreSQL incorrectly validated oidvector types. An attacker could possibly use this issue to obtain a few bytes of sensitive information. (CVE-2026-2003)

Daniel Firer discovered that PostgreSQL incorrectly validated input in the intarray extension. An attacker could possibly use this issue to execute arbitrary code. (CVE-2026-2004)

It was dicovered that PosgreSQL incorrectly handled certain pgcrypto memory operations. An attacker could possibly use this issue to execute arbitrary code. (CVE-2026-2005)

Paul Gerste and Moritz Sanft discovered that PostgreSQL incorrectly validated multibyte character lengths. An attacker could possibly use this issue to execute arbitrary code. (CVE-2026-2006)
