DLA 3054-1: sleuthkit security update

- -------------------------------------------------------------------------
Debian LTS Advisory DLA-3054-1 Andreas Rönnquist
June 20, 2022
- -------------------------------------------------------------------------

Package : sleuthkit
Version : 4.4.0-5+deb9u1
CVE ID : CVE-2017-13755 CVE-2017-13756 CVE-2017-13760 CVE-2018-19497
CVE-2020-10232 CVE-2019-1010065
Debian Bug :

Brief introduction


Opening a crafted ISO 9660 image triggers an out-of-bounds
read in iso9660_proc_dir() in tsk/fs/iso9660_dent.c in libtskfs.a, as
demonstrated by fls.


Opening a crafted disk image triggers infinite recursion in
dos_load_ext_table() in tsk/vs/dos.c in libtskvs.a, as demonstrated by


fls hangs on a corrupt exfat image in tsk_img_read() in
tsk/img/img_io.c in libtskimg.a.


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).


Prevent a stack buffer overflow in yaffsfs_istat by
increasing the buffer size to the size required by tsk_fs_time_to_str.


The Sleuth Kit 4.6.0 and earlier is affected by: Integer
Overflow. The impact is: Opening crafted disk image triggers crash in
tsk/fs/hfs_dent.c:237. The component is: Overflow in fls tool used on HFS
image. Bug is in tsk/fs/hfs.c file in function hfs_cat_traverse() in lines:
952, 1062. The attack vector is: Victim must open a crafted HFS filesystem

For Debian 9 stretch, these problems have been fixed in version

We recommend that you upgrade your sleuthkit packages.
