Synopsis

Type/Severity

Security Advisory Important

Topic

Updated postgresql92-postgresql packages that fix multiple security issues are now available for Red Hat Software Collections 1.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Description

PostgreSQL is an advanced object-relational database management system (DBMS).

Multiple stack-based buffer overflow flaws were found in the date/time implementation of PostgreSQL. An authenticated database user could provide a specially crafted date/time value that, when processed, could cause PostgreSQL to crash or, potentially, execute arbitrary code with the permissions of the user running PostgreSQL. (CVE-2014-0063)

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in various type input functions in PostgreSQL. An authenticated database user could possibly use these flaws to crash PostgreSQL or, potentially, execute arbitrary code with the permissions of the user running PostgreSQL. (CVE-2014-0064)

Multiple potential buffer overflow flaws were found in PostgreSQL. An authenticated database user could possibly use these flaws to crash PostgreSQL or, potentially, execute arbitrary code with the permissions of the user running PostgreSQL. (CVE-2014-0065)

It was found that granting an SQL role to a database user in a PostgreSQL database without specifying the "ADMIN" option allowed the grantee to remove other users from their granted role. An authenticated database user could use this flaw to remove a user from an SQL role which they were granted access to. (CVE-2014-0060)

A flaw was found in the validator functions provided by PostgreSQL's procedural languages (PLs). An authenticated database user could possibly use this flaw to escalate their privileges. (CVE-2014-0061)

A race condition was found in the way the CREATE INDEX command performed multiple independent lookups of a table that had to be indexed. An authenticated database user could possibly use this flaw to escalate their privileges. (CVE-2014-0062)

It was found that the chkpass extension of PostgreSQL did not check the return value of the crypt() function. An authenticated database user could possibly use this flaw to crash PostgreSQL via a null pointer dereference. (CVE-2014-0066)

Red Hat would like to thank the PostgreSQL project for reporting these issues. Upstream acknowledges Noah Misch as the original reporter of CVE-2014-0060 and CVE-2014-0063, Heikki Linnakangas and Noah Misch as the original reporters of CVE-2014-0064, Peter Eisentraut and Jozef Mlich as the original reporters of CVE-2014-0065, Andres Freund as the original reporter of CVE-2014-0061, Robert Haas and Andres Freund as the original reporters of CVE-2014-0062, and Honza Horak and Bruce Momjian as the original reporters of CVE-2014-0066.

These updated packages upgrade PostgreSQL to version 9.2.7, which fixes these issues as well as several non-security issues. Refer to the PostgreSQL Release Notes for a full list of changes:
