CVE-2024-10977
Description
A flaw was found in PostgreSQL's error message handling. This vulnerability allows a Man-in-the-middle attacker to inject arbitrary non-NUL bytes into the libpq application via a server error message.
Statement
This vulnerability affects PostgreSQL clients that handle error messages from untrusted servers, which may cause error messages to be misinterpreted as valid query results.
Mitigation
Make sure PostgreSQL is configured to use trusted SSL or GSS settings to prevent untrusted servers from sending error messages.
Additionally, when interpreting output from the psql command line interface, make sure to distinguish between error messages and valid data.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
