Detailsinfo

A vulnerability was found in PostgreSQL psqlODBC up to 18.00.5 and classified as problematic. This issue affects an unknown part of the component Log File. The manipulation with an unknown input leads to a permission assignment vulnerability. Using CWE to declare the problem leads to CWE-732. The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

On Unix-like systems, when logging is enabled, psqlODBC creates its log files in /tmp by default, named from the program name, user name, and process ID, with the default permissions, typically world-readable, and follows symbolic links when opening them. A local user can read query text and data from another user's logs, and can place a symbolic link at the predictable path so that the driver appends log data to a file of the attacker's choosing with the victim's privileges. Versions before psqlODBC 18.00.0006 are affected.
