From 43a694ab071f32609c0ea5c086d2a43f22c2ba55 Mon Sep 17 00:00:00 2001 From: Douglas Bagnall <douglas.bagnall@catalyst.net.nz> Date: Tue, 8 Dec 2020 22:00:55 +1300 Subject: [PATCH 01/17] CVE-2020-25718 ldb/attrib_handler casefold: simplify space dropping As seen in CVE-2021-20277, ldb_handler_fold() has been making mistakes when collapsing spaces down to a single space. This patch fixes the way it handles internal spaces (CVE-2021-20277 was about leading spaces), and involves a rewrite of the parsing loop. The bug has a detailed description of the problem.

While most chunks match the first suitable string, the last chunk matches the last possible string (unless there is a trailing asterisk, in which case this distinction is moot). We always knew this in our hearts, but we tried to do it in a funny complicated way that stepped through the string, comparing here and there, leading to CVE-2019-3824 and missed matches (bug 14044). With this patch, we just jump to the end of the string and compare it. As well as being correct, this should also improve performance, as the previous algorithm involved a quadratic loop of erroneous memmem()s.
