Revision b7052cd7bcf3c1478796e93e3dff2b44c9e82943 authored by Stefan Hajnoczi on 18 February 2016, 18:55:54 UTC, committed by J. Bruce Fields on 23 February 2016, 18:20:16 UTC
The qword_get() function NUL-terminates its output buffer. If the input
string is in hex format \xXXXX... and the same length as the output
buffer, there is an off-by-one:
int qword_get(char **bpp, char *dest, int bufsize)
{
...
while (len < bufsize) {
...
*dest++ = (h << 4) | l;
len++;
}
...
*dest = '\0';
return len;
}
This patch ensures the NUL terminator doesn't fall outside the output
buffer.
