CVSS: 7.0EPSS: 0%CPEs: 11EXPL: 0CVE-2018-1053 – postgresql: pg_upgrade creates file of sensitive metadata under prevailing umask
https://notcve.org/view.php?id=CVE-2018-1053
In postgresql 9.3.x before 9.3.21, 9.4.x before 9.4.16, 9.5.x before 9.5.11, 9.6.x before 9.6.7 and 10.x before 10.2, pg_upgrade creates file in current working directory containing the output of `pg_dumpall -g` under umask which was in effect when the user invoked pg_upgrade, and not under 0077 which is normally used for other temporary files. This can allow an authenticated attacker to read or modify the one file, which may contain encrypted or unencrypted database passwords. The attack is infeasible if a directory mode blocks the attacker searching the current working directory or if the prevailing umask blocks the attacker opening the file. En postgresql, en versiones 9.3.x anteriores a la 9.3.21, versiones 9.4.x anteriores a la 9.4.16, versiones 9.5.x anteriores a la 9.5.11, versiones 9.6.x anteriores a la 9.6.7 y en versiones 10.x anteriores a la 10.2, pg_upgrade crea archivos en el directorio de trabajo actual que contienen la salida de "pg_dumpall -g" bajo umask, que estaba en funcionamiento cuando el usuario invocó a pg_upgrade y no bajo 0077, que es el directorio que se suele emplear para otros archivos temporales. Esto puede permitir que un atacante autenticado lea o modifique un archivo que puede contener contraseñas cifradas o sin cifrar de la base de datos. • http://www.securityfocus.com/bid/102986 https://access.redhat.com/errata/RHSA-2018:2511 https://access.redhat.com/errata/RHSA-2018:2566 https://access.redhat.com/errata/RHSA-2018:3816 https://lists.debian.org/debian-lts-announce/2018/02/msg00006.html https://usn.ubuntu.com/3564-1 https://www.postgresql.org/about/news/1829 https://access.redhat.com/security/cve/CVE-2018-1053 https://bugzilla.redhat.com/show_bug.cgi?id=1539619 • CWE-377: Insecure Temporary File CWE-732: Incorrect Permission Assignment for Critical Resource •

https://notcve.org/view.php?id=CVE-2017-12172
PostgreSQL 10.x before 10.1, 9.6.x before 9.6.6, 9.5.x before 9.5.10, 9.4.x before 9.4.15, 9.3.x before 9.3.20, and 9.2.x before 9.2.24 runs under a non-root operating system account, and database superusers have effective ability to run arbitrary code under that system account. PostgreSQL provides a script for starting the database server during system boot. Packages of PostgreSQL for many operating systems provide their own, packager-authored startup implementations. Several implementations use a log file name that the database superuser can replace with a symbolic link. As root, they open(), chmod() and/or chown() this log file name. • http://www.securityfocus.com/bid/101949 http://www.securitytracker.com/id/1039752 https://access.redhat.com/errata/RHSA-2017:3402 https://access.redhat.com/errata/RHSA-2017:3403 https://access.redhat.com/errata/RHSA-2017:3404 https://access.redhat.com/errata/RHSA-2017:3405 https://www.postgresql.org/about/news/1801 https://www.postgresql.org/support/security https://access.redhat.com/security/cve/CVE-2017-12172 https://bugzilla.redhat.com/show_bug.cgi?id=1498394 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

The Debian pg_ctlcluster, pg_createcluster, and pg_upgradecluster scripts, as distributed in the Debian postgresql-common package before 181+deb9u1 for PostgreSQL (and other packages related to Debian and Ubuntu), handled symbolic links insecurely, which could result in local denial of service by overwriting arbitrary files. Los scripts de Debian pg_ctlcluster, pg_createcluster y pg_upgradecluster, tal y como se distribuyen en el paquete de Debian postgresql-common anterior a 181+deb9u1 para PostgreSQL (y otros paquetes relacionados con Debian y Ubuntu), manipularon vínculos simbólicos de forma no segura, lo que podría desembocar en una denegación de servicio local sobrescribiendo archivos arbitrarios. • http://metadata.ftp-master.debian.org/changelogs/main/p/postgresql-common/postgresql-common_181+deb9u1_changelog http://www.securityfocus.com/bid/101810 https://usn.ubuntu.com/usn/usn-3476-1 https://www.debian.org/security/2017/dsa-4029 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
