Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU64092
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-46790
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in the ntfsck in NTFS-3G when processing specially crafted NTFS filesystem. A local user can mount a malicious NTFS filesystem, trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.

2) Heap-based buffer overflow
EUVDB-ID: #VU63796
Risk: Low
CVSSv3.1: 5.8 [CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-30784
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in ntfs_get_attribute_value. A remote administrator can use a specially crafted NTFS image file, 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.
