CVE-2019-10208

Published: 8 August 2019

A flaw was discovered in postgresql versions 9.4.x before 9.4.24, 9.5.x before 9.5.19, 9.6.x before 9.6.15, 10.x before 10.10 and 11.x before 11.5 where arbitrary SQL statements can be executed given a suitable SECURITY DEFINER function. An attacker, with EXECUTE permission on the function, can execute arbitrary SQL as the owner of the function.

From the Ubuntu Security Team

Tom Lane discovered that PostgreSQL did not properly restrict functions declared as "SECURITY DEFINER". An attacker could use this to execute arbitrary SQL with the permissions of the function owner.

AuthorNote
leosilva
since 9.3 is not supported anymore by upstream
and for now we don't have how to patch it
I'm marking it as ignored.
