CVE-2022-41946
Description
A flaw was found in org.postgresql. This issue allows the creation of a temporary file when using PreparedStatement.setText(int, InputStream) and PreparedStatemet.setBytea(int, InputStream). This could allow a user to create an unexpected file available to all users, which could end in unexpected behavior.
Statement
Red Hat Satellite ships a PostgreSQL JDBC Driver for Hibernate ORM framework, which is embeds into Candlepin. Although Candlepin itself doesn't make direct use of the PreparedStatement methods from the PostgreSQL JDBC Driver, Hibernate ORM does utilize these methods, potentially making framework affected. Satellite server operating in an environment with untrusted users while the driver is running are vulnerable to the flaw, however, deployments without untrusted users are considered safe. A future Satellite update should address this issue.
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).

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Since the file is visible and the application which is using the temp file could be known, the attacker has gained information about what the user is doing at that time.
