Ubuntu 22.04 LTS / 23.04 : u-boot-nezha vulnerability (USN-6523-1)

high Nessus Plugin ID 186443

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 23.04 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6523-1 advisory.

 - Das U-Boot 2022.01 has a Buffer Overflow, a different issue than CVE-2022-30552. (CVE-2022-30790)

 - Das U-Boot 2022.01 has a Buffer Overflow. (CVE-2022-30552)

 - 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-2022-2347)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected u-boot-nezha package.
