aadd0a998d1f2db81a1c115cf7617428cb68b328b2051e91f2e2de0940ce8305Red Hat Security Advisory 2012-0678-01 - PostgreSQL is an advanced object-relational database management system. The pg_dump utility inserted object names literally into comments in the SQL script it produces. An unprivileged database user could create an object whose name includes a newline followed by an SQL command. This SQL command might then be executed by a privileged user during later restore of the backup dump, allowing privilege escalation. When configured to do SSL certificate verification, PostgreSQL only checked the first 31 characters of the certificate's Common Name field. Depending on the configuration, this could allow an attacker to impersonate a server or a client using a certificate from a trusted Certificate Authority issued for a different name.

Permissions on a function called by a trigger are not properly checked. SSL certificate name checks are truncated to 32 characters, allowing connection spoofing under some circumstances when using third party certificate authorities. Line breaks in object names can be exploited to execute arbitrary SQL when reloading a pg_dump file. This advisory provides the latest versions of PostgreSQL that is not vulnerable to these issues.
58823cceba466692ad13c21cdfd598a07b7adba85c277925ad3952248d6683a2Ubuntu Security Notice 1378-1 - It was discovered that PostgreSQL incorrectly checked permissions on functions called by a trigger. An attacker could attach a trigger to a table they owned and possibly escalate privileges. It was discovered that PostgreSQL incorrectly truncated SSL certificate name checks to 32 characters. If a host name was exactly 32 characters, this issue could be exploited by an attacker to spoof the SSL certificate. This issue affected Ubuntu 10.04 LTS, Ubuntu 10.10, Ubuntu 11.04 and Ubuntu 11.10. Various other issues were also addressed.
