-Subject: [PATCH] syntax.c: check for syntax element inconsistencies
-
-Implicit channel mapping reconfiguration is explicitely forbidden by
-ISO/IEC 13818-7:2006 (8.5.3.3). Decoders should be able to detect such
-files and reject them. FAAD2 does not perform any kind of checks
-regarding this.
-
-This leads to security vulnerabilities when processing crafted AAC
-files performing such reconfigurations.
-
-Add checks to decode_sce_lfe and decode_cpe to make sure such
-inconsistencies are detected as early as possible.
-
-These checks first read hDecoder->frame: if this is not the first
-frame then we make sure that the syntax element at the same position
-in the previous frame also had element_id id_syn_ele. If not, return
-21 as this is a fatal file structure issue.
-
-This patch addresses CVE-2018-20362 (fixes #26) and possibly other
-related issues.

-Subject: [PATCH] sbr_hfadj: sanitize frequency band borders
-
-user passed f_table_lim contains frequency band borders. Frequency
-bands are groups of consecutive QMF channels. This means that their
-bounds, as provided by f_table_lim, should never exceed MAX_M (maximum
-number of QMF channels). c.f. ISO/IEC 14496-3:2001
-
-FAAD2 does not verify this, leading to security issues when
-processing files defining f_table_lim with values > MAX_M.
-
-This patch sanitizes the values of f_table_lim so that they can be safely
-used as index for Q_M_lim and G_lim arrays.
-
-Fixes #21 (CVE-2018-20194).

-Subject: [PATCH] add patch to prevent crash on SCE followed by CPE
-
-hDecoder->element_alloced denotes whether or not we have allocated memory for
-usage in terms of the specified channel element. Given that it previously only
-had two states (1 meaning allocated, and 0 meaning not allocated), it would not
-allocate enough memory for parsing a CPE it if is preceeded by a SCE (and
-therefor crash).
-
-These changes fixes the issue by making sure that we allocate additional memory
-if so is necessary, and the set of values for hDecoder->element_alloced[n] is
-now:
-
- 0 = nothing allocated
- 1 = allocated enough for SCE
- 2 = allocated enough for CPE
-
-All branches that depend on hDecoder->element_alloced[n] prior to this patch
-only checks if the value is, or is not, zero. The added state, 2, is therefor
-correctly handled automatically.
