Description

This security bulletin contains information about 5 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2021-46790)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The 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 (CVE-ID: CVE-2022-30784)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The 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.


3) Heap-based buffer overflow (CVE-ID: CVE-2022-30786)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in ntfs_names_full_collate. 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.


4) Heap-based buffer overflow (CVE-ID: CVE-2022-30788)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in ntfs_mft_rec_alloc. 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.


5) Heap-based buffer overflow (CVE-ID: CVE-2022-30789)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to execute arbitrary code with escalated privileges.

The vulnerability exists due to a boundary error in the ntfs_check_log_client_array in NTFS-3G. A local attacker can mount a specially crafted NTFS image, trigger a heap-based buffer overflow and execute arbitrary code with escalated privileges.
