Last modified Jun 17, 2026

CVE-2018-19497 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. In The Sleuth Kit (TSK) through 4.6.4, hfs_cat_traverse in tsk/fs/hfs.c does not properly determine when a key length is too large, which allows attackers to cause a denial of service (SEGV on unknown address with READ memory access in a tsk_getu16 call in hfs_dir_open_meta_cb in tsk/fs/hfs_dent.c).. EPSS estimates a 1.52% chance of exploitation in the next 30 days.
