Summary
postgresql-10, postgresql-12, postgresql-9.5 vulnerabilities
Details
Noah Misch discovered that PostgreSQL incorrectly handled the search_path setting when used with logical replication. A remote attacker could possibly use this issue to execute arbitrary SQL code. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-14349)
Andres Freund discovered that PostgreSQL incorrectly handled search path elements in CREATE EXTENSION. A remote attacker could possibly use this issue to execute arbitrary SQL code. (CVE-2020-14350)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
