Description Adam Mariš 2018-06-08 11:58:37 UTC

An issue was discovered in libtskbase.a in The Sleuth Kit (TSK) from release 4.0.2 through to 4.6.1. An out-of-bounds read of a memory region was found in the function tsk_UTF16toUTF8 in tsk/base/tsk_unicode.c which could be leveraged by an attacker to disclose information or manipulated to read from unmapped memory causing a denial of service attack.
