It was discovered that the PostgreSQL database performs insufficient validation of variables passed to privileged SQL statements, so called security definers, which could lead to SQL privilege escalation. The oldstable distribution (sarge) doesn't contain PostgreSQL 8.1. For the stable distribution (etch) this problem has been fixed in version 8.1.9-0etch1. For the unstable distribution (sid) this problem has been fixed in version 8.1.9-1. We recommend that you upgrade your PostgreSQL packages.
