Date: May 9, 2024
Vim before 9.1.0404 has a buffer-overlow in xxd with colored output in xxd.c.When outputting colored hexdumps using the -R command line flag, together with -g1 (group every byte), -c 256 (format 256 octets per line), -d (show offsets in decimal) and -o <large_numer> (add offset to the file position), the buffer used to write to may overflow. User must intentionally execute xxd with several non-default flags, but it may cause a crash of xxd.
