+Subject: [PATCH] basenc: fix bug49741: using wrong decoding buffer length
+
+Emil Lundberg <lundberg.emil@gmail.com> reports in
+https://bugs.gnu.org/49741 about a 'basenc --base64 -d' decoding bug.
+The input buffer length was not divisible by 3, resulting in
+decoding errors.
+
+* NEWS: Mention fix.
+* src/basenc.c (DEC_BLOCKSIZE): Change from 1024*5 to 4200 (35*3*5*8)
+which is divisible by 3,4,5,8 - satisfying both base32 and base64;
+Use compile-time verify() macro to enforce the above.
+* tests/misc/basenc.pl: Add test.
