--- title: "CVE-2006-2314\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2006-2314?format=md keywords: index, follow --- # CVE-2006-2314 Publication date 24 May 2006 Last updated 17 July 2025 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description PostgreSQL 8.1.x before 8.1.4, 8.0.x before 8.0.8, 7.4.x before 7.4.13, 7.3.x before 7.3.15, and earlier versions allows context-dependent attackers to bypass SQL injection protection methods in applications that use multibyte encodings that allow the "\" (backslash) byte 0x5c to be the trailing byte of a multibyte character, such as SJIS, BIG5, GBK, GB18030, and UHC, which cannot be handled correctly by a client that does not understand multibyte encodings, aka a second variant of "Encoding-Based SQL Injection." NOTE: it could be argued that this is a class of issue related to interaction errors between the client and PostgreSQL, but a CVE has been assigned since PostgreSQL is treating this as a preventative measure against this class of problem. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | amarok | 7.04 feisty | Not affected | | 6.10 edgy | Not affected | | 6.06 LTS dapper | Not affected | | dovecot | 7.04 feisty | Fixed 1.0.rc17-1ubuntu2.1 | | 6.10 edgy | Fixed 1.0.rc2-1ubuntu2.2 | | 6.06 LTS dapper | Fixed 1.0.beta3-3ubuntu5.5 | | exim4 | 7.04 feisty | Ignored end of life, was needed | | 6.10 edgy | Ignored end of life, was needed | | 6.06 LTS dapper | Fixed 4.60-3ubuntu3.1 | | libapache2-mod-auth-pgsql | 7.04 feisty | Not affected | | 6.10 edgy | Not affected | | 6.06 LTS dapper | Not affected | | php5 | 7.04 feisty | Not affected | | 6.10 edgy | Not affected | | 6.06 LTS dapper | Not affected | | postfix | 7.04 feisty | Not affected | | 6.10 edgy | Not affected | | 6.06 LTS dapper | Fixed 2.2.10-1ubuntu0.1 | | postgresql | 7.04 feisty | Not in release | | 6.10 edgy | Not affected | | 6.06 LTS dapper | Not affected | | postgresql-7.4 | 7.04 feisty | Not in release | | 6.10 edgy | Fixed 7.4.13-4 | | 6.06 LTS dapper | Ignored end of life, was needed | | postgresql-8.1 | 7.04 feisty | Fixed 8.1.8-1ubuntu3 | | 6.10 edgy | Fixed 8.1.9-0ubuntu0.6.10 | | 6.06 LTS dapper | Fixed 8.1.9-0ubuntu0.6.06 | | postgresql-8.2 | 7.04 feisty | Fixed 8.2.4-0ubuntu0.7.04 | | 6.10 edgy | Not in release | | 6.06 LTS dapper | Not in release | | psycopg | 7.04 feisty | Fixed 1.1.21-3ubuntu3 | | 6.10 edgy | Fixed 1.1.21-3ubuntu3 | | 6.06 LTS dapper | Fixed 1.1.21-3ubuntu3 | | psycopg2 | 7.04 feisty | Fixed 2.0.5.1-1 | | 6.10 edgy | Fixed 2.0.5.1-1 | | 6.06 LTS dapper | Not in release | | pygresql | 7.04 feisty | Fixed 3.7-1ubuntu2 | | 6.10 edgy | Fixed 3.7-1ubuntu2 | | 6.06 LTS dapper | Fixed 3.7-1ubuntu2 | | python-pgsql | 7.04 feisty | Fixed 2.4.0-6ubuntu3 | | 6.10 edgy | Fixed 2.4.0-6ubuntu3 | | 6.06 LTS dapper | Fixed 2.4.0-6ubuntu3 | --- * [How can I get the fixes?](https://ubuntu.com/security/cves/about#security) * [What do statuses mean?](https://ubuntu.com/security/cves/about#statuses) ## References * [MITRE](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2314) * [NVD](https://nvd.nist.gov/vuln/detail/CVE-2006-2314) * [Launchpad](https://launchpad.net/bugs/cve/CVE-2006-2314) * [Debian](https://security-tracker.debian.org/tracker/CVE-2006-2314) ### Related Ubuntu Security Notices (USN) + [USN-288-2](https://usn.ubuntu.com/USN-288-2) + PostgreSQL server/client vulnerabilities + 9 June 2006 + [USN-288-3](https://usn.ubuntu.com/USN-288-3) + PostgreSQL client vulnerabilities + 9 June 2006 + [USN-288-1](https://usn.ubuntu.com/USN-288-1) + PostgreSQL server/client vulnerabilities + 29 May 2006 ### Other references *
