1.1.1Related CVE
| CVE ID | Published | Description | Score | Severity |
|---|---|---|---|---|
| U-Boot contains a CWE-20: Improper Input Validation vulnerability in Verified boot signature validation that can result in Bypass verified boot. This attack appear to be exploitable via Specially crafted FIT image and special device memory functionality. | 5.5 |
MEDIUM |
||
| In Das U-Boot through 2022.07-rc5, an integer signedness error and resultant stack-based buffer overflow in the "i2c md" command enables the corruption of the return address pointer of the do_i2c_md function. | 9.8 |
CRITICAL |
||
| nfs_lookup_reply in net/nfs.c in Das U-Boot through 2022.04 (and through 2022.07-rc2) has an unbounded memcpy with a failed length check, leading to a buffer overflow. NOTE: this issue exists because of an incorrect fix for CVE-2019-14196. | 9.8 |
CRITICAL |
||
| The boot loader in Das U-Boot before 2021.04-rc2 mishandles use of unit addresses in a FIT. | 7.8 |
HIGH |
||
| The boot loader in Das U-Boot before 2021.04-rc2 mishandles a modified FIT. | 7.8 |
HIGH |
||
| Das U-Boot through 2020.01 allows attackers to bypass verified boot restrictions and subsequently boot arbitrary images by providing a crafted FIT image to a system configured to boot the default configuration. | 7.8 |
HIGH |
||
| In Das U-Boot through 2020.01, a double free has been found in the cmd/gpt.c do_rename_gpt_parts() function. Double freeing may result in a write-what-where condition, allowing an attacker to execute arbitrary code. NOTE: this vulnerablity was introduced when attempting to fix a memory leak identified by static analysis. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with an unvalidated length at nfs_readlink_reply, in the "if" block after calculating the new path length. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy when parsing a UDP packet due to a net_process_received_packet integer underflow during an *udp_packet_handler call. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with a failed length check at nfs_lookup_reply. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is a read of out-of-bounds data at nfs_read_reply. | 9.1 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with a failed length check at nfs_read_reply when calling store_block in the NFSv3 case. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with unvalidated length at nfs_readlink_reply in the "else" block after calculating the new path length. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with a failed length check at nfs_read_reply when calling store_block in the NFSv2 case. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy when parsing a UDP packet due to a net_process_received_packet integer underflow during an nc_input_packet call. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this nfs_handler reply helper function: rpc_lookup_reply. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this nfs_handler reply helper function: nfs_lookup_reply. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this nfs_handler reply helper function: nfs_readlink_reply. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this nfs_handler reply helper function: nfs_mount_reply. | 9.8 |
CRITICAL |
||
| An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this nfs_handler reply helper function: nfs_umountall_reply. | 9.8 |
CRITICAL |
||
| A crafted self-referential DOS partition table will cause all Das U-Boot versions through 2019.07-rc4 to infinitely recurse, causing the stack to grow infinitely and eventually either crash or overwrite other data. | 7.1 |
HIGH |
||
| DENX U-Boot through 2018.09-rc1 has a remotely exploitable buffer overflow via a malicious TFTP server because TFTP traffic is mishandled. Also, local exploitation can occur via a crafted kernel image. | 9.8 |
CRITICAL |
||
| DENX U-Boot through 2018.09-rc1 has a locally exploitable buffer overflow via a crafted kernel image because filesystem loading is mishandled. | 7.8 |
HIGH |
||
| Das U-Boot is a device bootloader that can read its configuration from an AES encrypted file. For devices utilizing this environment encryption mode, U-Boot's use of a zero initialization vector may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data. Das U-Boot's AES-CBC encryption feature uses a zero (0) initialization vector. This allows an attacker to perform dictionary attacks on encrypted data produced by Das U-Boot to learn information about the encrypted data. | 4.6 |
MEDIUM |
||
| Das U-Boot is a device bootloader that can read its configuration from an AES encrypted file. Devices that make use of Das U-Boot's AES-CBC encryption feature using environment encryption (i.e., setting the configuration parameter CONFIG_ENV_AES=y) read environment variables from disk as the encrypted disk image is processed. An attacker with physical access to the device can manipulate the encrypted environment data to include a crafted two-byte sequence which triggers an error in environment variable parsing. This error condition is improperly handled by Das U-Boot, resulting in an immediate process termination with a debugging message. | 6.4 |
