Title: Joerg Wendland LibNSS-PgSQL Remote SQL Query Manipulation Vulnerability
Severity: MODERATE
Description:
Joerg Wendland's 'libnss-pgsql' is a NSS(Name Service Switch) module for PostgreSQL.
The NSS database module 'libnss-pgsql' is prone to a vulnerability which will allow SQL queries to be manipulated via any request which requires PAM authentication, regardless of the protocol used. Data that is included in SQL query strings is not adequately sanitized. It may be possible for users to modify the structure of SQL queries by carefully constructing variables containing metacharacters that will be included in the target query.
It is believed that the attacker would need an interactive account on the vulnerable host to exploit this issue. Attacks will be executed on the database server as the database user that is making the query.
This issue allows the user to access resources that would normally be restricted, which may in turn provide an opportunity for the attacker to exploit other vulnerabilities that exist in the server.

- Joerg Wendland libnss-pgsql 0.9.0
