Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Corruption: An uninitialized pointer access and buffer overflow vulnerability exists in the array decoding implementation. A malicious or compromised PostgreSQL server can return crafted multidimensional array metadata to trigger a client-side crash or potential arbitrary code execution, as tracked under CVE-2020-17446. Ensure strict validation of all dimensions and bound checks before decoding elements.
Auth Bypass: Insecure SSL fallback mechanisms can cause the connection process to implicitly trust system-default root certificate authorities despite explicit, restrictive SSL modes configured for PostgreSQL. This bypass allows potential machine-in-the-middle attacks if an attacker can obtain a certificate signed by any trusted system CA.
