Threats tagged 'ghsa-5wgw-m382-jcv2'

A buffer overflow vulnerability exists in psqlODBC versions before 18.00.0006 where the client copies data from a large-object read (loread) into its buffer using the length provided by the server without verifying the buffer size. This can allow a malicious or untrusted server to overwrite adjacent memory in the client process. Triggering the vulnerability requires fetching any large-object column.
