CVSS: 6.5EPSS: 0%CPEs: 10EXPL: 0CVE-2021-3677 – postgresql: memory disclosure in certain queries
https://notcve.org/view.php?id=CVE-2021-3677
A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. • https://bugzilla.redhat.com/show_bug.cgi?id=2001857 https://security.gentoo.org/glsa/202211-04 https://security.netapp.com/advisory/ntap-20220407-0008 https://www.postgresql.org/support/security/CVE-2021-3677 https://access.redhat.com/security/cve/CVE-2021-3677 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2021-32027
A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before 9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se ha encontrado un fallo en postgresql en las versiones anteriores a 13.3, versiones anteriores a 12.7, versiones anteriores a 11.12, versiones anteriores a 10.17 y versiones anteriores a 9.6.22. Cuando se modifican determinados valores de matrices SQL, una falta de comprobación de límites permite a usuarios autentificados de la base de datos escribir bytes arbitrarios en una amplia zona de la memoria del servidor. • https://bugzilla.redhat.com/show_bug.cgi?id=1956876 https://security.gentoo.org/glsa/202211-04 https://security.netapp.com/advisory/ntap-20210713-0004 https://www.postgresql.org/support/security/CVE-2021-32027 https://access.redhat.com/security/cve/CVE-2021-32027 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2019-10128
A vulnerability was found in postgresql versions 11.x prior to 11.3. The Windows installer for EnterpriseDB-supplied PostgreSQL does not lock down the ACL of the binary installation directory or the ACL of the data directory; it keeps the inherited ACL. In the default configuration, this allows a local attacker to read arbitrary data directory files, essentially bypassing database-imposed read access limitations. In plausible non-default configurations, an attacker having both an unprivileged Windows account and an unprivileged PostgreSQL account can cause the PostgreSQL service account to execute arbitrary code. Se encontró una vulnerabilidad en postgresql versiones 11.x anteriores a 11.3. • https://bugzilla.redhat.com/show_bug.cgi?id=1707102 https://security.netapp.com/advisory/ntap-20210430-0004 https://www.postgresql.org/about/news/1939 • CWE-284: Improper Access Control •

A vulnerability was found in postgresql versions 11.x prior to 11.3. The Windows installer for BigSQL-supplied PostgreSQL does not lock down the ACL of the binary installation directory or the ACL of the data directory; it keeps the inherited ACL. In the default configuration, an attacker having both an unprivileged Windows account and an unprivileged PostgreSQL account can cause the PostgreSQL service account to execute arbitrary code. An attacker having only the unprivileged Windows account can read arbitrary data directory files, essentially bypassing database-imposed read access limitations. An attacker having only the unprivileged Windows account can also delete certain data directory files. • https://bugzilla.redhat.com/show_bug.cgi?id=1707098 https://security.netapp.com/advisory/ntap-20210430-0004 https://www.postgresql.org/about/news/1939 • CWE-284: Improper Access Control •

A flaw was found in PostgreSQL in versions before 13.2. This flaw allows a user with SELECT privilege on one column to craft a special query that returns all columns of the table. The highest threat from this vulnerability is to confidentiality. Se ha encontrado un fallo en PostgreSQL en las versiones anteriores a la 13.2. Este fallo permite a un usuario con privilegio SELECT en una columna elaborar una consulta especial que devuelva todas las columnas de la tabla. • https://bugzilla.redhat.com/show_bug.cgi?id=1925296 https://security.gentoo.org/glsa/202105-32 https://security.netapp.com/advisory/ntap-20210326-0005 • CWE-863: Incorrect Authorization •
