Eclipse ThreadX

A denial-of-service vulnerability exists in the NetX IPv6 component functionality of Eclipse ThreadX NetX Duo. A specially crafted network packet of "Packet Too Big" with more than 15 different source address can lead to denial of service. An attacker can send a malicious packet to trigger this vulnerability.

The function _ux_host_class_storage_media_mount() is responsible for mounting partitions on a USB mass storage device. When it encounters an extended partition entry in the partition table, it recursively calls itself to mount the next logical partition. This recursion occurs in _ux_host_class_storage_partition_read(), which parses up to four partition entries. If an extended partition is found (with type UX_HOST_CLASS_STORAGE_PARTITION_EXTENDED or EXTENDED_LBA_MAPPED), the code invokes: _ux_host_class_storage_media_mount(storage, sector + _ux_utility_long_get(...)); There is no limit on the recursion depth or tracking of visited sectors. As a result, a malicious or malformed disk image can include cyclic or excessively deep chains of extended partitions, causing the function to recurse until stack overflow occurs.

In USBX before 6.4.3, the USB support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _ux_host_class_audio10_sam_parse_func() when parsing a list of sampling frequencies.

In USBX before 6.4.3, the USB support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _ux_host_class_audio_alternate_setting_locate() when parsing a descriptor with attacker-controlled frequency fields.

In USBX before 6.4.3, the USB support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _ux_host_class_audio_device_type_get() when parsing a descriptor of an USB audio device.

In USBX before 6.4.3, the USB support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _ux_host_class_audio_streaming_sampling_get() when parsing a descriptor of an USB streaming device.

In USBX before 6.4.3, the USB support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _ux_host_class_hid_report_descriptor_get()  when parsing a descriptor of an USB HID device.

In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _nx_icmpv6_validate_options() when handling a packet with ICMP6 options.

In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _nx_ipv4_packet_receive() when handling unicast DHCP messages that could cause corruption of 4 bytes of memory.

In Eclipse Foundation NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _nx_ipv4_option_process() when processing an IPv4 packet with the timestamp option.

In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _nx_ip_packet_receive() function when received an Ethernet with type set as IP but no IP data.

In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _nx_ipv4_packet_receive() function when received an Ethernet frame with less than 4 bytes of IP packet.

In NetX Duo version before 6.4.4, the component of Eclipse Foundation ThreadX, there was an incorrect bound check in_nx_secure_tls_proc_clienthello_supported_versions_extension() in the extension version field.

In NetX Duo version before 6.4.4, the component of Eclipse Foundation ThreadX, there was an incorrect bound check resulting it out by two out of bound read.
