Debian DSA-3476-1 : postgresql-9.4 - security update

high Nessus Plugin ID 88727
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been found in PostgreSQL-9.4, a SQL database system.

- CVE-2016-0766 A privilege escalation vulnerability for users of PL/Java was discovered. Certain custom configuration settings (GUCs) for PL/Java will now be modifiable only by the database superuser to mitigate this issue.

- CVE-2016-0773 Tom Lane and Greg Stark discovered a flaw in the way PostgreSQL processes specially crafted regular expressions. Very large character ranges in bracket expressions could cause infinite loops or memory overwrites. A remote attacker can exploit this flaw to cause a denial of service or, potentially, to execute arbitrary code.

Solution

Upgrade the postgresql-9.4 packages.

For the stable distribution (jessie), these problems have been fixed in version 9.4.6-0+deb8u1.
