-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2018.2362 postgresql-9.4 security update 16 August 2018 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: postgresql-9.4 Publisher: Debian Operating System: Debian GNU/Linux 8 Windows UNIX variants (UNIX, Linux, OSX) Impact/Access: Execute Arbitrary Code/Commands -- Existing Account Unauthorised Access -- Existing Account Resolution: Patch/Upgrade CVE Names: CVE-2018-10915 Original Bulletin: https://security-tracker.debian.org/tracker/DLA-1464-1 Comment: This advisory references vulnerabilities in products which run on platforms other than Debian. It is recommended that administrators running postgresql check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Package : postgresql-9.4 Version : 9.4.19-0+deb8u1 CVE ID : CVE-2018-10915 An unprivileged user of dblink or postgres_fdw could bypass the checks intended to prevent use of server-side credentials, such as a ~/.pgpass file owned by the operating-system user running the server. Servers allowing peer authentication on local connections are particularly vulnerable. Other attacks such as SQL injection into a postgres_fdw session are also possible. Attacking postgres_fdw in this way requires the ability to create a foreign server object with selected connection parameters, but any user with access to dblink could exploit the problem. In general, an attacker with the ability to select the connection parameters for a libpq-using application could cause mischief, though other plausible attack scenarios are harder to think of. Our thanks to Andrew Krasichkov for reporting this issue. For Debian 8 "Jessie", this problem has been fixed in version 9.4.19-0+deb8u1. We recommend that you upgrade your postgresql-9.4 packages.
