4 | Subject: [PATCH] Fix possible buffer overrun with invalid UTF-8 | ||
5 | |||
6 | An out of bounds read access in the UTF-8 decoding can be triggered with | ||
7 | a malformed file in the tool less. The access happens in the function | ||
8 | is_utf8_well_formed due to a truncated multibyte character in the sample | ||
9 | file. | ||
10 | |||
11 | The bug does not crash less, it can only be made visible by running less | ||
12 | with valgrind or compiling it with Address Sanitizer. | ||
13 | |||
14 | Version 475 of less contains a fix for this issue. The file version.c | ||
15 | contains some entry mentioning this issue (without any credit): | ||
16 | |||
17 | - v475 3/2/15 Fix possible buffer overrun with invalid UTF-8 | ||
18 | |||
19 | The fix is in the file line.c. We derive this patch from: | ||
