+Subject: [PATCH] rpmio: Fix lzopen_internal mode parsing when 'Tn' is used
+
+When there is number after "T" (suggested number of threads or "0" for
+getncpus), lzopen_internal() mode parser would skip one byte, and when
+it's at the end of the string it would then parse undesired garbage from
+the memory, making intermittent compression failures.
+
+Fixes: 7740d1098 ("Add support for multithreaded xz compression")
+Signed-off-by: Vitaly Chikunov <vt@altlinux.org>
+
+Upstream-Status: Backport [https://github.com/rpm-software-management/rpm/commit/405fc8998181353bd510864ca251dc233afec276]
