HIGH Summary
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).
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

NASL family Debian Local Security Checks NASL id DEBIAN_DLA-1610.NASL description It was discovered that the Sleuth Kit (TSK) through version 4.6.4 is affected by a buffer over-read vulnerability. The tsk_getu16 call in hfs_dir_open_meta_cb (tsk/fs/hfs_dent.c) does not properly check boundaries. This vulnerability might be leveraged by remote attackers using crafted filesystem images to cause denial of service or any other unspecified behavior.
