Synopsis
The remote SUSE host is missing one or more security updates.
Description
The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2971-1 advisory.
- An integer underflow issue exists in ntfs-3g 2017.3.23. A local attacker could potentially exploit this by running /bin/ntfs-3g with specially crafted arguments from a specially crafted directory to cause a heap buffer overflow, resulting in a crash or the ability to execute arbitrary code. In installations where /bin/ntfs-3g is a setuid-root binary, this could lead to a local escalation of privileges. (CVE-2019-9755)
- In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function ntfs_get_attribute_value, a heap buffer overflow can occur allowing for memory disclosure or denial of service. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the bytes_in_use field should be less than the bytes_allocated field. When it is not, the parsing of the records proceeds into the wild. (CVE-2021-33285)
- In NTFS-3G versions < 2021.8.22, when a specially crafted unicode string is supplied in an NTFS image a heap buffer overflow can occur and allow for code execution. (CVE-2021-33286)
- In NTFS-3G versions < 2021.8.22, when specially crafted NTFS attributes are read in the function ntfs_attr_pread_i, a heap buffer overflow can occur and allow for writing to arbitrary memory or denial of service of the application. (CVE-2021-33287)
- In NTFS-3G versions < 2021.8.22, when a specially crafted MFT section is supplied in an NTFS image a heap buffer overflow can occur and allow for code execution. (CVE-2021-33289)
- In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode pathname is supplied in an NTFS image a heap buffer overflow can occur resulting in memory disclosure, denial of service and even code execution. (CVE-2021-35266)
- NTFS-3G versions < 2021.8.22, a stack buffer overflow can occur when correcting differences in the MFT and MFTMirror allowing for code execution or escalation of privileges when setuid-root. (CVE-2021-35267)
- In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode is loaded in the function ntfs_inode_real_open, a heap buffer overflow can occur allowing for code execution and escalation of privileges. (CVE-2021-35268)
- NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute from the MFT is setup in the function ntfs_attr_setup_flag, a heap buffer overflow can occur allowing for code execution and escalation of privileges. (CVE-2021-35269)
- A crafted NTFS image can cause a NULL pointer dereference in ntfs_extent_inode_open in NTFS-3G < 2021.8.22. (CVE-2021-39251)
- A crafted NTFS image can cause an out-of-bounds read in ntfs_ie_lookup in NTFS-3G < 2021.8.22.
(CVE-2021-39252)
- A crafted NTFS image can cause an out-of-bounds read in ntfs_runlists_merge_i in NTFS-3G < 2021.8.22.
(CVE-2021-39253)
- A crafted NTFS image can trigger an out-of-bounds read, caused by an invalid attribute in ntfs_attr_find_in_attrdef, in NTFS-3G < 2021.8.22. (CVE-2021-39255)
- A crafted NTFS image can cause a heap-based buffer overflow in ntfs_inode_lookup_by_name in NTFS-3G < 2021.8.22. (CVE-2021-39256)
- A crafted NTFS image with an unallocated bitmap can lead to a endless recursive function call chain (starting from ntfs_attr_pwrite), causing stack consumption in NTFS-3G < 2021.8.22. (CVE-2021-39257)
- A crafted NTFS image can cause out-of-bounds reads in ntfs_attr_find and ntfs_external_attr_find in NTFS-3G < 2021.8.22. (CVE-2021-39258)
- A crafted NTFS image can trigger an out-of-bounds access, caused by an unsanitized attribute length in ntfs_inode_lookup_by_name, in NTFS-3G < 2021.8.22. (CVE-2021-39259)
- A crafted NTFS image can cause an out-of-bounds access in ntfs_inode_sync_standard_information in NTFS-3G < 2021.8.22. (CVE-2021-39260)
- A crafted NTFS image can cause a heap-based buffer overflow in ntfs_compressed_pwrite in NTFS-3G < 2021.8.22. (CVE-2021-39261)
- A crafted NTFS image can cause an out-of-bounds access in ntfs_decompress in NTFS-3G < 2021.8.22.
(CVE-2021-39262)
- A crafted NTFS image can trigger a heap-based buffer overflow, caused by an unsanitized attribute in ntfs_get_attribute_value, in NTFS-3G < 2021.8.22. (CVE-2021-39263)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update the affected libntfs-3g-devel, libntfs-3g87, ntfs-3g and / or ntfsprogs packages.
