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)
