CVE-2007-3278: Debian Linux

Medium severity, CVSS 6.9. EPSS: 1.3% chance of exploitation in the next 30 days.

PostgreSQL 8.1 and probably later versions, when local trust authentication is enabled and the Database Link library (dblink) is installed, allows remote attackers to access arbitrary accounts and execute arbitrary SQL queries via a dblink host parameter that proxies the connection from 127.0.0.1.

Affected products

• Debian Debian Linux: version 3.1 only; version 4.0 only
• PostgreSQL PostgreSQL: from 7.3, before 7.3.21 (fixed in 7.3.21); from 7.4, before 7.4.19 (fixed in 7.4.19); from 8.0, before 8.0.15 (fixed in 8.0.15); from 8.1, before 8.1.11 (fixed in 8.1.11); from 8.2, before 8.2.6 (fixed in 8.2.6)
