CVE-2019-14192 1Denx 1U Boot Jun 17, 2026 Jul 31, 2019 N/A· v4 9.8 CRITICAL· v3 7.5 HIGH· v2 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.
CVE-2019-13103 1Denx 1U Boot Jun 17, 2026 Jul 29, 2019 N/A· v4 7.1 HIGH· v3 3.6 LOW· v2 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.
CVE-2019-11059 1Denx 1U Boot Jun 17, 2026 May 10, 2019 N/A· v4 9.8 CRITICAL· v3 7.5 HIGH· v2 Das U-Boot 2016.11-rc1 through 2019.04 mishandles the ext4 64-bit extension, resulting in a buffer overflow.
CVE-2019-11690 1Denx 1U Boot Jun 17, 2026 May 3, 2019 N/A· v4 5.9 MEDIUM· v3 4.3 MEDIUM· v2 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...Show more 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.Show less
CVE-2018-3968 1Denx 1U Boot Nov 21, 2024 Mar 21, 2019 N/A· v4 7.0 HIGH· v3 4.4 MEDIUM· v2 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 bypa...Show more 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.Show less
CVE-2018-18440 1Denx 1U Boot Nov 21, 2024 Nov 20, 2018 N/A· v4 7.8 HIGH· v3 7.2 HIGH· v2 DENX U-Boot through 2018.09-rc1 has a locally exploitable buffer overflow via a crafted kernel image because filesystem loading is mishandled.
CVE-2018-18439 1Denx 1U Boot Nov 21, 2024 Nov 20, 2018 N/A· v4 9.8 CRITICAL· v3 10.0 HIGH· v2 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.
CVE-2017-3226 1Denx 1U Boot Nov 21, 2024 Jul 24, 2018 N/A· v4 6.4 MEDIUM· v3 4.4 MEDIUM· v2 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...Show more 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.Show less
CVE-2017-3225 1Denx 1U Boot Nov 21, 2024 Jul 24, 2018 N/A· v4 4.6 MEDIUM· v3 2.1 LOW· v2 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...Show more 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.Show less
CVE-2018-1000205 1Denx 1U Boot Nov 21, 2024 Jun 26, 2018 N/A· v4 5.5 MEDIUM· v3 4.3 MEDIUM· v2 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 sp...Show more 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.Show less
