Publication date: 13 Apr 2016
Modification date: 13 Apr 2016
Type: security
Affected Mageia releases : 5
CVE: CVE-2016-2193 , CVE-2016-3065

Description

Updated postgresql packages fix security vulnerabilities:

A vulnerability in PostgreSQL 9.3.x before 9.3.12 and 9.4.x before 9.4.7 leads
to potentially incorrect policies being applied in cases where role-specific
policies are used and a given query is planned under one role and then executed
under other roles, which could happen under security definer functions or when
a common user and query is planned initially and then re-used across multiple
SET ROLEs. Applying an incorrect policy may permit a user to complete
otherwise-forbidden reads and modifications. This affects only databases that
have used CREATE POLICY to define a row security policy (CVE-2016-2193).

A vulnerability was found in a way PostgreSQL 9.3.x before 9.3.12 and 9.4.x
before 9.4.7 uses pageinspect functions. Certain function arguments crashed
the server or disclosed a few bytes of server memory. The viability of attacks
that arrange for presence of confidential information in the disclosed bytes
was not ruled out. This affects only databases that have used "CREATE
EXTENSION pageinspect" (CVE-2016-3065).
