CVE-2017-3225 1 Denx 1 U-boot 2019-10-09 2.1 LOW 4.6 MEDIUM
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.
CVE-2017-3226 1 Denx 1 U-boot 2019-10-09 4.4 MEDIUM 6.4 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.
CVE-2019-13106 1 Denx 1 U-boot 2019-10-01 8.3 HIGH 7.8 HIGH
Das U-Boot versions 2016.09 through 2019.07-rc4 can memset() too much data while reading a crafted ext4 filesystem, which results in a stack buffer overflow and likely code execution.
CVE-2019-13105 1 Denx 1 U-boot 2019-08-13 6.8 MEDIUM 7.8 HIGH
Das U-Boot versions 2019.07-rc1 through 2019.07-rc4 can double-free a cached block of data when listing files in a crafted ext4 filesystem.
CVE-2019-14199 1 Denx 1 U-boot 2019-08-02 7.5 HIGH 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.
CVE-2019-14197 1 Denx 1 U-boot 2019-08-02 6.4 MEDIUM 9.1 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.
CVE-2019-11059 1 Denx 1 U-boot 2019-05-13 7.5 HIGH 9.8 CRITICAL
Das U-Boot 2016.11-rc1 through 2019.04 mishandles the ext4 64-bit extension, resulting in a buffer overflow.
CVE-2019-11690 1 Denx 1 U-boot 2019-05-06 4.3 MEDIUM 5.9 MEDIUM
gen_rand_uuid in lib/uuid.c in Das U-Boot v2014.04 through v2019.04 lacks an srand call, which allows attackers to determine UUID values in scenarios where CONFIG_RANDOM_UUID is enabled, and Das U-Boot is relied upon for UUID values of a GUID Partition Table of a boot device.
CVE-2018-3968 1 Denx 1 U-boot 2019-04-02 4.4 MEDIUM 7.0 HIGH
An exploitable vulnerability exists in the verified boot protection of the Das U-Boot from version 2013.07-rc1 to 2014.07-rc2. The affected versions lack proper FIT signature enforcement, which allows an attacker to bypass U-Boot's verified boot and execute an unsigned kernel, embedded in a legacy image format. To trigger this vulnerability, a local attacker needs to be able to supply the image to boot.
CVE-2018-18439 1 Denx 2 Das U-boot, Das U-boot Firmware 2019-01-02 10.0 HIGH 9.8 CRITICAL
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.
