1) NULL pointer dereference
EUVDB-ID: #VU96001
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-7006
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in tif_dirinfo.c. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
MitigationInstall updates from vendor's repository.

2) Out-of-bounds write
EUVDB-ID: #VU86755
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-52356
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input within the TIFFReadRGBATileExt() API. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds write and execute arbitrary code on the target system.
MitigationInstall updates from vendor's repository.

3) Heap-based buffer overflow
EUVDB-ID: #VU86757
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-6228
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the cpStripToTile() function in libtiff/tools/tiffcp.c. A remote attacker can pass a specially crafted TIFF image to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
