DescriptionCVE.org

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.

AnalysisAI

Arbitrary code execution in PostgreSQL results from insufficient validation of multibyte character lengths in text manipulation functions, allowing authenticated database users to trigger buffer overflows and execute commands with database process privileges. Affected versions include PostgreSQL 14.x before 14.21, 15.x before 15.16, 16.x before 16.12, 17.x before 17.8, and all versions before 18.2. No patch is currently available, leaving databases vulnerable to privilege escalation attacks from database-level users.

Technical ContextAI

Classified as CWE-129 (Improper Validation of Array Index). Affects Postgresql. 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.

RemediationAI

Monitor vendor advisories for a patch. Restrict network access to the affected service where possible.
