Vulnerability from variot

Contiki-NG is an open-source, cross-platform operating system for Next-Generation IoT devices. An out-of-bounds read can be triggered by 6LoWPAN packets sent to devices running Contiki-NG 4.6 and prior. The IPv6 header decompression function (uncompress_hdr_iphc) does not perform proper boundary checks when reading from the packet buffer. Hence, it is possible to construct a compressed 6LoWPAN packet that will read more bytes than what is available from the packet buffer. As of time of publication, there is not a release with a patch available. Users can apply the patch for this vulnerability out-of-band as a workaround. Contiki-NG Is vulnerable to an out-of-bounds read.Information is obtained and denial of service (DoS) It may be put into a state.

The 6LoWPAN implementation in Contiki-NG 4.6 and earlier versions has an out-of-bounds read vulnerability. No detailed vulnerability details are currently provided. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. Contiki-NG has a buffer error vulnerability, which originates from the 6LoWPAN message of devices of 4.6 and above that will trigger a read out of range
