Ubuntu 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.
