USN-1378-1: PostgreSQL vulnerabilities

28 February 2012

postgresql-8.3, postgresql-8.4, postgresql-9.1 vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 11.10
  • Ubuntu 11.04
  • Ubuntu 10.10
  • Ubuntu 10.04 LTS
  • Ubuntu 8.04 LTS

Summary

Several security issues were fixed in PostgreSQL.

Software Description

  • postgresql-9.1 - Object-relational SQL database
  • postgresql-8.4 - Object-relational SQL database
  • postgresql-8.3 - Object-relational SQL database

Details

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. (CVE-2012-0866)

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. (CVE-2012-0867)

It was discovered that the PostgreSQL pg_dump utility incorrectly filtered line breaks in object names. An attacker could create object names that execute arbitrary SQL commands when a dump script is reloaded. (CVE-2012-0868)
