Announcement ID: SUSE-SU-2018:2564-1
Rating: moderate
References: #1091610 #1104199 #1104202
Cross-References: CVE-2018-10915 CVE-2018-10925 CVE-2018-1115
Affected Products:
  • SUSE Linux Enterprise Module for Server Applications 15
  • SUSE Linux Enterprise Module for Basesystem 15

An update that fixes three vulnerabilities is now available.

Description:

This update for postgresql10 fixes the following issues:
PostgreSQL 10 was updated to 10.5:

  • https://www.postgresql.org/about/news/1851/
  • https://www.postgresql.org/docs/current/static/release-10-5.html

A dump/restore is not required for those running 10.X. However, if you use the adminpack extension, you should update it as per the first changelog entry below. Also, if the function marking mistakes mentioned in the second and third changelog entries below affect you, you will want to take steps to correct your database catalogs.
Security issues fixed:
  • CVE-2018-1115: Remove public execute privilege from contrib/adminpack's pg_logfile_rotate() function pg_logfile_rotate() is a deprecated wrapper for the core function pg_rotate_logfile(). When that function was changed to rely on SQL privileges for access control rather than a hard-coded superuser check, pg_logfile_rotate() should have been updated as well, but the need for this was missed. Hence, if adminpack is installed, any user could request a logfile rotation, creating a minor security issue. After installing this update, administrators should update adminpack by performing ALTER EXTENSION adminpack UPDATE in each database in which adminpack is installed (bsc#1091610).
  • CVE-2018-10915: libpq failed to properly reset its internal state between connections. If an affected version of libpq was used with "host" or "hostaddr" connection parameters from untrusted input, attackers could have bypassed client-side connection security features, obtain access to higher privileged connections or potentially cause other impact SQL injection, by causing the PQescape() functions to malfunction (bsc#1104199)
  • CVE-2018-10925: Add missing authorization check on certain statements involved with "INSERT ... ON CONFLICT DO UPDATE". An attacker with "CREATE TABLE" privileges could have exploited this to read arbitrary bytes server memory. If the attacker also had certain "INSERT" and limited "UPDATE" privileges to a particular table, they could have exploited this to update other columns in the same table (bsc#1104202).
