Ubuntu Security Notice USN-753-1
7th April, 2009
postgresql-8.1, postgresql-8.3 vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 8.10
- Ubuntu 8.04 LTS
- Ubuntu 6.06 LTS
It was discovered that PostgreSQL did not properly handle encoding
conversion failures. An attacker could exploit this by sending specially
crafted requests to PostgreSQL, leading to a denial of service.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 8.10:
- postgresql-8.3 8.3.7-0ubuntu8.10.1
- Ubuntu 8.04 LTS:
- postgresql-8.3 8.3.7-0ubuntu8.04.1
- Ubuntu 6.06 LTS:
- postgresql-8.1 8.1.17-0ubuntu0.6.06.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
This update uses a new upstream release, which includes additional
bug fixes. In general, a standard system upgrade is sufficient to
effect the necessary changes.
