BIT-postgresql-2023-5870 — Postgresql: role pg_signal_backend can signal certain superuser processes.

Affected: Bitnami: postgresql

A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.

Withdrawn: CLEANSTART-2026-AI42483 — PostgreSQL optimizer statistics allow a user to read sampled data within a view that the user cannot access

Withdrawn by the publisher.

Affected: CleanStart: postgresql

Multiple security vulnerabilities affect the postgresql package. PostgreSQL optimizer statistics allow a user to read sampled data within a view that the user cannot access. See references for individual vulnerability details.

ICSA-24-228-06 — Siemens SINEC NMS

A use-after-free flaw was found in mm/mempolicy.c in the memory management subsystem in the Linux Kernel. This issue is caused by a race between mbind() and VMA-locked page fault, and may allow a local attacker to crash the system or lead to a kernel information leak. A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive information by exploiting certain aggregate function calls with 'unknown'-type arguments. Handling 'unknown'-type values from string literals without type designation can disclose bytes, potentially revealing notable and confidential information. This issue exists due to excessive data output in aggregate function calls, enabling remote users to read some portion of system memory. A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through missing overflow checks during SQL array value modification. This issue exists due to an integer overflow during array modification where a remote user can trigger the overflow by providing specially crafted data. This enables the execution of arbitrary code on the target system, allowing users to write arbitrary bytes to memory and extensively read the server's memory.
