commit 5da11db4cd9058bbec13a3096e7597727798a627
Author: Ralph Boehme <slow at samba.org>
Date: Fri Nov 26 07:19:32 2021 +0100
CVE-2021-44142: libadouble: harden ad_unpack_xattrs()
This ensures ad_unpack_xattrs() is only called for an ad_type of ADOUBLE_RSRC,
which is used for parsing ._ AppleDouble sidecar files, and the buffer
ad->ad_data is AD_XATTR_MAX_HDR_SIZE bytes large which is a prerequisite for all
buffer out-of-bounds access checks in ad_unpack_xattrs().
