Ubuntu Security Notice USN-2772-1
October 16, 2015
postgresql-9.1, postgresql-9.3, postgresql-9.4 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
Summary:
PostgreSQL could be made to crash or expose private information if it
handled specially crafted data.
Software Description:
- postgresql-9.4: Object-relational SQL database
- postgresql-9.3: Object-relational SQL database
- postgresql-9.1: Object-relational SQL database
Details:
Josh Kupershmidt discovered the pgCrypto extension could expose
several bytes of server memory if the crypt() function was provided a
too-short salt. An attacker could use this flaw to read private data.
(CVE-2015-5288)
Oskari Saarenmaa discovered that the json and jsonb handlers could exhaust
available stack space. An attacker could use this flaw to perform a denial
of service attack. This issue only affected Ubuntu 14.04 LTS and Ubuntu
15.04. (CVE-2015-5289)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 15.04:
postgresql-9.4 9.4.5-0ubuntu0.15.04
Ubuntu 14.04 LTS:
postgresql-9.3 9.3.10-0ubuntu0.14.04
Ubuntu 12.04 LTS:
postgresql-9.1 9.1.19-0ubuntu0.12.04
This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart PostgreSQL to
make all the necessary changes.
