A vulnerability was found in a way PostgreSQL uses pageinspect functions. Certain function arguments crashed the server or disclosed a few bytes of server memory. The viability of attacks that arrange for presence of confidential information in the disclosed bytes was not ruled out. This affects only databases that have used "CREATE EXTENSION pageinspect".
Name: the PostgreSQL project
Upstream: Andreas Seltenreich
