<pre>I looked for dependent packages in oe-core and in meta-oe with grep and found only enchant
and enchant2 although I was able to build both of them having the aspell patch applied.
Best regards,

+Subject: [PATCH 1/2] Don't allow null-terminated UCS-2/4 strings
using the
+ original API.
+
+Detect if the encoding is UCS-2/4 and the length is -1 in affected
API
+functions and refuse to convert the string. If the string ends up
+being converted somehow, abort with an error message in DecodeDirect
+and ConvDirect. To convert a null terminated string in
+Decode/ConvDirect, a negative number corresponding to the width of
the
+underlying character type for the encoding is expected; for example,
+if the encoding is "ucs-2" then a the size is expected to be -2.
+
+Also fix a 1-3 byte over-read in DecodeDirect when reading UCS-2/4
+strings when a size is provided (found by OSS-Fuzz).
+
+Also fix a bug in DecodeDirect that caused DocumentChecker to return
+the wrong offsets when working with UCS-2/4 strings.
+
+CVE: CVE-2019-20433

++@appendixsec Upgrading from Aspell 0.60.7
++
++To prevent a potentially unbounded buffer over-read, Aspell no
longer
++supports null-terminated UCS-2 and UCS-4 encoded strings with the
++original C API. Null-termianted 8-bit or UTF-8 encoded strings are
++still supported, as are UCS-2 and UCS-4 encoded strings when the
++length is passed in.
++
++As of Aspell 0.60.8 a function from the original API that expects
an
++encoded string as a parameter will return meaningless results (or
an
++error code) if string is null terminated and the encoding is set to
++@code{ucs-2} or @code{ucs-4}. In addition, a single:
++@example
++ERROR: aspell_speller_check: Null-terminated wide-character strings
unsupported when used this way.
++@end example
++will be printed to standard error the first time one of those
++functions is called.
++
++Application that use null-terminated UCS-2/4 strings should either
(1)
++use the interface intended for working with wide-characters
++(@xref{Through the C API}); or (2) define
++@code{ASPELL_ENCODE_SETTING_SECURE} before including
@code{aspell.h}.
++In the latter case is is important that the application explicitly
++sets the encoding to a known value. Defining
++@code{ASPELL_ENCODE_SETTING_SECURE} and not setting the encoding
++explicitly or allowing user of the application to set the encoding
++could result in an unbounded buffer over-read.
++
++If it is necessary to preserve binary compatibility with older
++versions of Aspell, the easiest thing would be to determine the
length
++of the UCS-2/4 string---in bytes---and pass that in. Due to an
++implemenation detail, existing API functions can be made to work
with
++null-terminated UCS-2/4 strings safely by passing in either @code{-
2}
++or @code{-4} (corresponding to the width of the character type) as
the
++size. Doing so, however, will cause a buffer over-read for
unpatched
++version of Aspell. To avoid this it will be necessary to parse the
++version string to determine the correct value to use. However, no
++official support will be provided for the latter method.
++
++If the application can not be recompiled, then Aspell can be
configured
++to preserve the old behavior by passing
++@option{--enable-sloppy-null-term-strings} to
@command{configure}. When Aspell
++is compiled this way the version string will include the string

+ Support for being able to load additional filter modules at run-
time
+ has only been verified to work on Linux platforms. If you get
linker
+ errors when trying to use a filter, then it is likely that loadable
+ filter support is not working yet on your platform. Thus, in order
to
+ get Aspell to work correctly you will need to avoid compiling the
+ filters as individual modules by using the
+-@option{--enable-compile-in-filters} when configuring Aspell with
+-@command{./configure}.
++@option{--enable-compile-in-filters} @command{configure} option.
