Description

This security bulletin contains information about 9 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: N/A)

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

CVSSv4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the ntfs_ie_add_vcn() function within the libntfs-3g/index.c file. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.


2) Heap-based buffer overflow (CVE-ID: N/A)

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

CVSSv4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the ntfs_acl_owner() function. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.


3) Heap-based buffer overflow (CVE-ID: N/A)

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

CVSSv4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the ntfs_acl_owner() function. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.


4) Heap-based buffer overflow (CVE-ID: N/A)

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

CVSSv4: 7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local attacker to compromise the target system.

The vulnerability exists due to a boundary error in the ntfs_same_sid() function. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and gain access to sensitive information or perform a denial of service (DoS) attack.


5) Infinite loop (CVE-ID: N/A)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in the ntfs_inode_attach_all_extents() function. A local attacker can consume all available system resources and cause denial of service conditions.


6) Heap-based buffer overflow (CVE-ID: N/A)

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

CVSSv4: 2.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the ntfs_check_restart_area() function. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.


7) Heap-based buffer overflow (CVE-ID: N/A)

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

CVSSv4: 2.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local attacker to compromsie the target system.

The vulnerability exists due to a boundary error in the ntfs_ea_check_wsldev() function. A local attacker can cause leakage of heap data outside the memory allocation.


8) Heap-based buffer overflow (CVE-ID: N/A)

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

CVSSv4: 2.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the ntfs_external_attr_find() function within libntfs-3g/attrib.c file. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.


9) Heap-based buffer overflow (CVE-ID: N/A)

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

CVSSv4: 2.1 [CVSS:4.0/AV:L/AC:H/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local attacker to compromise the target system.

The vulnerability exists due to a boundary error in the ntfs_mapping_pairs_decompress_i() function in runlist.c file. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause subsequent read and write operations to access unintended locations.
