Echo: libusb-1.0: security update to 2:1.0.28-1+e1

medium Tenable Cloud Security Plugin ID 457660

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- libusb before version 1.0.30 contains a one-byte out-of-bounds read vulnerability in parse_iad_array() in
descriptor.c that allows attackers to trigger a denial of service by supplying a malformed USB descriptor
whose bLength equals size minus one, causing the bounds check to use the original buffer size instead of
the remaining size. Attackers in virtualized environments with USB passthrough can supply crafted
descriptors through libusb_get_active_interface_association_descriptors or
libusb_get_interface_association_descriptors to read one byte past the end of the malloc allocation,
resulting in a denial of service. (CVE-2026-47104)

Solution

Update the libusb-1.0 library and its related packages to version 2:1.0.28-1+e1 or later.
