The Sleuth Kit through 4.15.0 NULL Pointer Dereference via decmpfs LZVN Decompression

The Sleuth Kit through 4.15.0 contains a NULL pointer dereference vulnerability in decmpfs_decompress_lzvn_attr() that allows attackers to crash the tool by supplying a crafted HFS+ image. Attackers can set a huge uncompressed_size in an LZVN inline com.apple.decmpfs attribute so allocation fails and the decoder writes through NULL, causing denial of service.

The Sleuth Kit through 4.15.0 Heap Out-of-Bounds Read via HFS+ decmpfs Header

The Sleuth Kit through 4.15.0 contains a heap out-of-bounds read vulnerability in hfs_load_extended_attrs() in tsk/fs/hfs.c that reads the decmpfs header without checking attribute length. Attackers can supply a crafted HFS+ image with a com.apple.decmpfs attr_size of 1 to 15 to read past the allocation and crash analysis tools like istat or icat.

Sleuth Kit ISO9660 SUSP Extension Reference Out-of-Bounds Read

The Sleuth Kit through 4.14.0 contains an out-of-bounds read vulnerability in the ISO9660 filesystem parser where the parse_susp() function trusts len_id, len_des, and len_src fields from the disk image to memcpy data into a stack buffer without verifying that the source data falls within the parsed SUSP block. An attacker can craft a malicious ISO image that causes reads past the end of the SUSP data buffer, and a zero-length SUSP entry can trigger an infinite parsing loop.

Sleuth Kit tsk_recover Path Traversal

The Sleuth Kit through 4.14.0 contains a path traversal vulnerability in tsk_recover that allows an attacker to write files to arbitrary locations outside the intended recovery directory via crafted filenames or directory paths with path traversal sequences in a filesystem image. An attacker can craft a malicious filesystem image with embedded /../ sequences in filenames that, when processed by tsk_recover, writes files outside the output directory, potentially achieving code execution by overwriting shell configuration or cron entries.

Sleuth Kit APFS Keybag Parser Out-of-Bounds Read

The Sleuth Kit through 4.14.0 contains an out-of-bounds read vulnerability in the APFS filesystem keybag parser where the wrapped_key_parser class follows attacker-controlled length fields without bounds checking, causing heap reads past the allocated buffer. An attacker can craft a malicious APFS disk image that triggers information disclosure or crashes when processed by any Sleuth Kit tool that parses APFS volumes.

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.

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.

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.

The Sleuth Kit (TSK) 4.0.1 does not properly handle "." (dotfile) file system entries in FAT file systems and other file systems for which . is not a reserved name, which allows local users to hide activities it more difficult to conduct forensics activities, as demonstrated by Flame.

OS Command injection vulnerability in sleuthkit fls tool 4.11.1 allows attackers to execute arbitrary commands via a crafted value to the m parameter. NOTE: third parties have disputed this because there is no analysis showing that the backtick command executes outside the context of the user account that entered the command line.

In version 4.8.0 and earlier of The Sleuth Kit (TSK), there is a heap-based buffer over-read in ntfs_dinode_lookup in fs/ntfs.c.

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.

An issue was discovered in The Sleuth Kit (TSK) 4.6.6. There is an off-by-one overwrite due to an underflow on tools/hashtools/hfind.cpp while using a bogus hash table.

An issue was discovered in The Sleuth Kit (TSK) 4.6.6. There is an out of bounds read on iso9660 while parsing System Use Sharing Protocol data in fs/iso9660.c.

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.

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).

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.

An issue was discovered in libtskimg.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 raw_read in tsk/img/raw.c which could be leveraged by an attacker to disclose information or manipulated to read from unmapped memory causing a denial of service attack.

An issue was discovered in libtskfs.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 ntfs_make_data_run in tsk/fs/ntfs.c which could be leveraged by an attacker to disclose information or manipulated to read from unmapped memory causing a denial of service attack.

An issue was discovered in libtskfs.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 ntfs_fix_idxrec in tsk/fs/ntfs_dent.cpp which could be leveraged by an attacker to disclose information or manipulated to read from unmapped memory causing a denial of service.
