CVE-2023-2455 (GCVE-0-2023-2455)

Vulnerability from – Published: 2023-06-09 00:00 – Updated: 2025-01-06 17:13

Summary

Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect policies to be applied in certain cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects only databases that have used CREATE POLICY to define a row security policy.

Severity ?

5.4 (Medium)

CVE-2018-12121 (GCVE-0-2018-12121)

Vulnerability from – Published: 2018-11-28 17:00 – Updated: 2024-12-27 16:02

Summary

Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Denial of Service with large HTTP headers: By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer.
