CVE-2022-2347 1 Denx 1 U-boot 2023-12-10 N/A 7.1 HIGH
There exists an unchecked length field in UBoot. The U-Boot DFU implementation does not bound the length field in USB DFU download setup packets, and it does not verify that the transfer direction corresponds to the specified command. Consequently, if a physical attacker crafts a USB DFU download setup packet with a `wLength` greater than 4096 bytes, they can write beyond the heap-allocated request buffer.
CVE-2022-33967 1 Denx 1 U-boot 2023-12-10 N/A 7.8 HIGH
squashfs filesystem implementation of U-Boot versions from v2020.10-rc2 to v2022.07-rc5 contains a heap-based buffer overflow vulnerability due to a defect in the metadata reading process. Loading a specially crafted squashfs image may lead to a denial-of-service (DoS) condition or arbitrary code execution.
CVE-2022-30552 1 Denx 1 U-boot 2023-12-10 2.1 LOW 5.5 MEDIUM
Das U-Boot 2022.01 has a Buffer Overflow.
CVE-2022-30767 2 Denx, Fedoraproject 2 U-boot, Fedora 2023-12-10 7.5 HIGH 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.
CVE-2022-34835 1 Denx 1 U-boot 2023-12-10 7.5 HIGH 9.8 CRITICAL
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.
CVE-2022-33103 1 Denx 1 U-boot 2023-12-10 4.6 MEDIUM 7.8 HIGH
Das U-Boot from v2020.10 to v2022.07-rc3 was discovered to contain an out-of-bounds write via the function sqfs_readdir().
CVE-2022-30790 1 Denx 1 U-boot 2023-12-10 7.2 HIGH 7.8 HIGH
Das U-Boot 2022.01 has a Buffer Overflow, a different issue than CVE-2022-30552.
CVE-2021-27138 1 Denx 1 U-boot 2023-12-10 6.8 MEDIUM 7.8 HIGH
The boot loader in Das U-Boot before 2021.04-rc2 mishandles use of unit addresses in a FIT.
CVE-2021-27097 1 Denx 1 U-boot 2023-12-10 6.8 MEDIUM 7.8 HIGH
The boot loader in Das U-Boot before 2021.04-rc2 mishandles a modified FIT.
CVE-2020-10648 2 Denx, Opensuse 2 U-boot, Leap 2023-12-10 6.8 MEDIUM 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.
CVE-2020-8432 2 Denx, Opensuse 2 U-boot, Leap 2023-12-10 10.0 HIGH 9.8 CRITICAL
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.
CVE-2019-13103 1 Denx 1 U-boot 2023-12-10 3.6 LOW 7.1 HIGH
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-2019-13105 1 Denx 1 U-boot 2023-12-10 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-2019-14193 1 Denx 1 U-boot 2023-12-10 7.5 HIGH 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.
CVE-2019-11059 1 Denx 1 U-boot 2023-12-10 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 2023-12-10 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-2019-14192 1 Denx 1 U-boot 2023-12-10 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 nc_input_packet call.
CVE-2019-14203 1 Denx 1 U-boot 2023-12-10 7.5 HIGH 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.
CVE-2019-14202 1 Denx 1 U-boot 2023-12-10 7.5 HIGH 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.
CVE-2019-13106 2 Denx, Opensuse 2 U-boot, Leap 2023-12-10 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.
