| | | | | | | If xmbrtowc() fails, or if xiswprint() is false, then we shouldn't include that wide char in the printable length. Fixes: 19c96abe0a1ee56cf206fd5e87defb1fd3e0daa5
* bfstd: Fix an OOB string index in xmbrtowc()Tavian Barnes2023-09-061-6/+2
| | | | | | | | | | | | | | | | | | | | | | This bug could be reproduced with something like $ bfs -samefile $'\xFA\xFA' bfs: error: bfs: dstrnescat@src/dstring.c:252: wordesc() result truncated or worse, with -DNDEBUG, $ bfs -samefile $'.....................\xFA\xFA' bfs: error: bfs -samefile $'.....................\xFA\xFA\x00\x55\x53\x45\x52\x3D\x74\x61\x76\x69\x61\x6E\x61\x74\x6F\x72 bfs: error: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ bfs: error: No such file or directory. which prints the memory after the end of the string (in this case, the environment variable USER=tavianator). The bug was caused by the line `*i += len`, which was intended to be `*i = len`. But actually, the right behaviour seems to be `*i += 1`. Fixes: 19c96abe0a1ee56cf206fd5e87defb1fd3e0daa5
