Title
Buffer Over-read when receiving improperly sized ICMPv6 packets in FreeRTOS-Plus-TCP
Summary
A missing validation check in FreeRTOS-Plus-TCP's ICMPv6 packet processing code can lead to an out-of-bounds read when receiving ICMPv6 packets of certain message types which are smaller than the expected size. These issues only affect applications using IPv6.
Users should upgrade to the latest version and ensure any forked or derivative code is patched to incorporate the new fixes.

Title
OOBR and OOBW in pcap_ether_aton() in libpcap
Summary
pcap_ether_aton() is an auxiliary function in libpcap, it takes a string argument and returns a fixed-size allocated buffer. The string argument must be a well-formed MAC-48 address in one of the supported formats, but this requirement has been poorly documented. If an application calls the function with an argument that deviates from the expected format, the function can read data beyond the end of the provided string and write data beyond the end of the allocated buffer.
