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.

According to the versions of the uboot-tools packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - DENX U-Boot through 2018.09-rc1 has a locally exploitable buffer overflow via a crafted kernel image     because filesystem loading is mishandled. (CVE-2018-18440)

  - Das U-Boot 2016.11-rc1 through 2019.04 mishandles the ext4 64-bit extension, resulting in a buffer     overflow. (CVE-2019-11059)

  - 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-2019-11690)

  - 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-2019-13103)

  - 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-2019-13104)

  - 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-2019-13106)

  - 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-2019-14192)

  - 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-2019-14193)

  - 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. (CVE-2019-14194)

  - 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. (CVE-2019-14195)

  - 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. (CVE-2019-14196)

  - 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-2019-14197)

  - 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. (CVE-2019-14198)

  - 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-2019-14199)

  - 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. (CVE-2019-14200)

  - 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-2019-14201)

  - 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-2019-14202)

  - 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-2019-14203)

  - 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. (CVE-2019-14204)
