From 74d36a57c5fe65e5447f61a6ed0b57c6bb7c4f0f Mon Sep 17 00:00:00 2001 From: Lasse Collin Date: Tue, 7 May 2024 19:56:46 +0300 Subject: [PATCH] liblzma: Set all values in lzma_lz_encoder to NULL after allocation. This is unlikely to be a bug in an existing application since it relies on calling lzma_filters_update() on an LZMA1 encoder in the first place. For instance, it does not affect xz because lzma_filters_update() can only be used when encoding to the .xz format.
