Description

Altran picoTCP through 1.7.0 allows memory corruption (and subsequent denial of service) because of an integer overflow in pico_ipv6_alloc when processing large ICMPv6 packets. This affects installations with Ethernet support in which a packet size greater than 65495 may occur.

Integer Overflow or Wraparound

The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
