CVE-2023-5868

Public on 2023-11-12
Modified on 2024-03-13
Description

Certain aggregate function calls receiving "unknown"-type arguments could disclose bytes of server memory from the end of the "unknown"-type value to the next zero byte. One typically gets an "unknown"-type value via a string literal having no type designation. We have not confirmed or ruled out viability of attacks that arrange for presence of notable, confidential information in disclosed bytes.
