CVE-2019-13106 2 Denx, Opensuse 2 U-boot, Leap 2023-03-03 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-2018-3968 1 Denx 1 U-boot 2023-02-02 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 1 U-boot 2023-01-23 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.
CVE-2022-30767 2 Denx, Fedoraproject 2 U-boot, Fedora 2022-10-27 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-2022-2347 1 Denx 1 U-boot 2022-09-29 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 2022-08-02 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-2022-33103 1 Denx 1 U-boot 2022-07-15 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-2022-34835 1 Denx 1 U-boot 2022-07-08 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-2022-30790 1 Denx 1 U-boot 2022-06-16 7.2 HIGH 7.8 HIGH
Das U-Boot 2022.01 has a Buffer Overflow, a different issue than CVE-2022-30552.
CVE-2022-30552 1 Denx 1 U-boot 2022-06-16 2.1 LOW 5.5 MEDIUM
Das U-Boot 2022.01 has a Buffer Overflow.
CVE-2019-13104 2 Denx, Opensuse 2 U-boot, Leap 2022-04-18 6.8 MEDIUM 7.8 HIGH
In Das U-Boot versions 2016.11-rc1 through 2019.07-rc4, an underflow can cause memcpy() to overwrite a very large amount of data (including the whole stack) while reading a crafted ext4 filesystem.
CVE-2020-8432 2 Denx, Opensuse 2 U-boot, Leap 2021-07-21 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-2020-10648 2 Denx, Opensuse 2 U-boot, Leap 2021-03-26 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-2021-27138 1 Denx 1 U-boot 2021-02-23 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 2021-02-23 6.8 MEDIUM 7.8 HIGH
The boot loader in Das U-Boot before 2021.04-rc2 mishandles a modified FIT.
CVE-2018-1000205 1 Denx 1 U-boot 2020-10-22 4.3 MEDIUM 5.5 MEDIUM
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.
CVE-2019-14201 1 Denx 1 U-boot 2020-08-24 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_lookup_reply.
CVE-2019-13103 1 Denx 1 U-boot 2020-08-24 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-2019-14192 1 Denx 1 U-boot 2020-08-24 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-2019-14193 1 Denx 1 U-boot 2020-08-24 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.
