An issue was discovered in Squid before 4.9. URN response handling in Squid
suffers from a heap-based buffer overflow. When receiving data from a
remote server in response to an URN request, Squid fails to ensure that the
response can fit within the buffer. This leads to attacker controlled data
overflowing in the heap.
