patch 9.1.0094: xxd: buffer-overflow when writing color output
Problem: xxd: buffer-overflow when writing color output
Solution: properly account for the color escape sequences and
adjust LLEN macro
(Goffredo Baroncelli)
xxd: crash with higer number of column
xxd writes the data into a buffer before printing. Unfortunately
the buffer doesn't consider the space consumed by the escape
sequences used to change the color of the character.
BEFORE:
$ xxd -Ralways -c 256 /etc/passwd
Segmentation fault (core dumped)
AFTER:
$ ./xxd -Ralways -c 256 /etc/passwd
00000000: 726f 6f74 3a78 3a30 3a30 3a72 6f6f 743a 2f72 [...]
To solve this issue I had to increase the size of the buffer
considering for each byte of data 11 further characters for the
color escape sequence.
