[ASA-201908-8] postgresql: multiple issues
Arch Linux Security Advisory ASA-201908-8 ========================================= Severity: Medium Date : 2019-08-10 CVE-ID : CVE-2019-10208 CVE-2019-10209 Package : postgresql Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1019 Summary ======= The package postgresql before version 11.5-1 is vulnerable to multiple issues including access restriction bypass and information disclosure. Resolution ========== Upgrade to 11.5-1. # pacman -Syu "postgresql>=11.5-1" The problems have been fixed upstream in version 11.5. Workaround ========== None. Description =========== - CVE-2019-10208 (access restriction bypass) A security issue has been found in PostgreSQL < 11.5 where given a suitable SECURITY DEFINER function, an attacker can execute arbitrary SQL under the identity of the function owner. An attack requires EXECUTE permission on the function, which must itself contain a function call having inexact argument type match. For example, length('foo'::varchar) and length('foo') are inexact, while length('foo'::text) is exact. As part of exploiting this vulnerability, the attacker uses CREATE DOMAIN to create a type in a pg_temp schema. The attack pattern and fix are similar to that for CVE-2007-2138. - CVE-2019-10209 (information disclosure) An issue has been found in PostgreSQL >= 11.0 and < 11.5. In a database containing hypothetical, user-defined hash equality operators, an attacker could read arbitrary bytes of server memory. For an attack to become possible, a superuser would need to create unusual operators. It is possible for operators not purpose-crafted for attack to have the properties that enable an attack, but we are not aware of specific examples. Impact ====== An authenticated attacker can read arbitrary bytes of server memory or execute arbitrary SQL commands under a different identity than its own.
