CVE-2026-119923
Heap-based Buffer Overflow in Babelfish for PostgreSQL TDS Prelogin Parser
شرح رسمی (انگلیسی)
A heap-based buffer overflow in the TDS prelogin parser in the Babelfish for PostgreSQL extension versions 1.0-1.5, 2.1-2.15, 3.1-3.12, 4.0-4.8, 5.1-5.4 and in Amazon Aurora PostgreSQL with Babelfish might allow remote attackers to execute arbitrary OS commands as the database process user via a specially crafted malformed TDS prelogin packet to the TDS port. This record consolidates a related NULL-pointer-dereference finding in the same prelogin parser. To remediate this issue, we recommend users upgrade to Babelfish for PostgreSQL extension versions 4.10, 5.6, 6.1 or later. As a workaround, restrict network access to the TDS port (default 1433). Customers using Amazon Aurora PostgreSQL with Babelfish should upgrade their cluster to Aurora PostgreSQL 13.9.16 (1.5.5), 13.23.3 (1.17.2), 14.6.16 (2.3.5), 14.17.8 (2.12.4), 14.18.6 (2.13.3), 14.19.5 (2.14.2), 14.20.5 (2.15.2), 14.22.3 (2.16.1), 14.23.1 (2.17.0), 15.10.8 (3.8.4), 15.12.8 (3.9.4), 15.13.6 (3.10.3), 15.14.5 (3.11.2), 15.15.5 (3.12.2), 15.17.3 (3.13.1), 15.18.1 (3.14.0), 16.8.8 (4.5.5), 16.9.6 (4.6.3), 16.10.5 (4.7.2), 16.11.5 (4.8.2), 16.13.3 (4.9.1), 16.14.1 (4.10.0), 17.4.8 (5.1.4), 17.5.6 (5.2.3), 17.6.5 (5.3.2), 17.7.5 (5.4.2), 17.9.3 (5.5.1), 17.10.1 (5.6.0), 18.3.4 (6.0.2), 18.4.1 (6.1.0) or later, and apply any pending maintenance to ensure they are on the latest patch.
