Description
The liblnk_data_string_get_utf8_string_size function in liblnk_data_string.c in liblnk through 2018-04-19 allows remote attackers to cause an information disclosure (heap-based buffer over-read) via a crafted lnk file. NOTE: the vendor has disputed this as described in libyal/liblnk issue 33 on GitHub
