dla-3054 advisory.

  - In The Sleuth Kit (TSK) 4.4.2, 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. (CVE-2017-13755)

  - In The Sleuth Kit (TSK) 4.4.2, opening a crafted disk image triggers infinite recursion in
    dos_load_ext_table() in tsk/vs/dos.c in libtskvs.a, as demonstrated by mmls. (CVE-2017-13756)

  - In The Sleuth Kit (TSK) 4.4.2, fls hangs on a corrupt exfat image in tsk_img_read() in tsk/img/img_io.c in
    libtskimg.a. (CVE-2017-13760)

  - 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). (CVE-2018-19497)

  - 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 image. (CVE-2019-1010065)

  - In version 4.8.0 and earlier of The Sleuth Kit (TSK), there is a stack buffer overflow vulnerability in
    the YAFFS file timestamp parsing logic in yaffsfs_istat() in fs/yaffs.c. (CVE-2020-10232)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
