-Subject: [PATCH] Fix possible buffer overrun with invalid UTF-8
-
-An out of bounds read access in the UTF-8 decoding can be triggered with
-a malformed file in the tool less. The access happens in the function
-is_utf8_well_formed due to a truncated multibyte character in the sample
-file.
-
-The bug does not crash less, it can only be made visible by running less
-with valgrind or compiling it with Address Sanitizer.
-
-Version 475 of less contains a fix for this issue. The file version.c
-contains some entry mentioning this issue (without any credit):
-
- - v475 3/2/15 Fix possible buffer overrun with invalid UTF-8
-
-The fix is in the file line.c. We derive this patch from:
-
-https://blog.fuzzing-project.org/3-less-out-of-bounds-read-access-TFPA-0022014.html
-
-Thank Claire Robinson for validating it on Mageia 4 i586. Refer to:
