CVE-2026-2005 [HIGH] CVE-2026-2005: postgresql-13 - Heap buffer overflow in PostgreSQL pgcrypto allows a ciphertext provider to exec... Heap buffer overflow in PostgreSQL pgcrypto allows a ciphertext provider to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. Scope: local bullseye: resolved (fixed in 13.23-0+deb11u2)

CVE-2026-2004 [HIGH] CVE-2026-2004: postgresql-13 - Missing validation of type of input in PostgreSQL intarray extension selectivity... Missing validation of type of input in PostgreSQL intarray extension selectivity estimator function allows an object creator to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. Scope: local bullseye: resolved (fixed in 13.23-0+deb11u2)

CVE-2026-2006 [HIGH] CVE-2026-2006: postgresql-13 - Missing validation of multibyte character length in PostgreSQL text manipulation... Missing validation of multibyte character length in PostgreSQL text manipulation allows a database user to issue crafted queries that achieve a buffer overrun. That suffices to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. Scope: local bullseye: resolved (fix

CVE-2026-2003 [MEDIUM] CVE-2026-2003: postgresql-13 - Improper validation of type "oidvector" in PostgreSQL allows a database user to ... Improper validation of type "oidvector" in PostgreSQL allows a database user to disclose a few bytes of server memory. We have not ruled out viability of attacks that arrange for presence of confidential information in disclosed bytes, but they seem unlikely. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. Scope: local bullseye: re

CVE-2026-2007 [HIGH] CVE-2026-2007: postgresql-13 - Heap buffer overflow in PostgreSQL pg_trgm allows a database user to achieve unk... Heap buffer overflow in PostgreSQL pg_trgm allows a database user to achieve unknown impacts via a crafted input string. The attacker has limited control over the byte patterns to be written, but we have not ruled out the viability of attacks that lead to privilege escalation. PostgreSQL 18.1 and 18.0 are affected. Scope: local bullseye: resolved

CVE-2025-12818 [MEDIUM] CVE-2025-12818: postgresql-13 - Integer wraparound in multiple PostgreSQL libpq client library functions allows ... Integer wraparound in multiple PostgreSQL libpq client library functions allows an application input provider or network peer to cause libpq to undersize an allocation and write out-of-bounds by hundreds of megabytes. This results in a segmentation fault for the application using libpq. Versions before PostgreSQL 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23 ar

CVE-2025-12817 [LOW] CVE-2025-12817: postgresql-13 - Missing authorization in PostgreSQL CREATE STATISTICS command allows a table own... Missing authorization in PostgreSQL CREATE STATISTICS command allows a table owner to achieve denial of service against other CREATE STATISTICS users by creating in any schema. A later CREATE STATISTICS for the same name, from a user having the CREATE privilege, would then fail. Versions before PostgreSQL 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23 are affected.
