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-2021-3393
An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a column they are allowed to write but not read. Se detectó un filtrado de información en postgresql en versiones anteriores a 13.2, versiones anteriores a 12.6 y versiones anteriores a 11.11. Un usuario que tenga el permiso UPDATE pero no el permiso SELECT para una columna en particular podría diseñar consultas que, en algunas circunstancias, podrían divulgar valores de esa columna en mensajes de error. • https://bugzilla.redhat.com/show_bug.cgi?id=1924005 https://security.gentoo.org/glsa/202105-32 https://security.netapp.com/advisory/ntap-20210507-0006 https://access.redhat.com/security/cve/CVE-2021-3393 • CWE-209: Generation of Error Message Containing Sensitive Information •
