APP: Squid WCCP Message Receive Buffer Overflow
This signature detects malformed WCCP datagrams. A vulnerability exists in the way the Squid Web proxy processes Web Cache Communication Protocol (WCCP) messages. An overly long UDP datagram can trigger a buffer overflow. This vulnerability can be exploited to terminate the vulnerable product, causing a denial-of-service condition or it can be exploited for code execution.
Extended Description
The Squid proxy server is vulnerable to a remotely exploitable buffer-overflow vulnerability. The vulnerability resides in Squid's implementation of WCCP (web cache communication protocol), a UDP-based web cache management protocol. The condition is triggered when the server reads a packet that is larger than the size of the buffer allocated to store it. This can occur because 'recvfrom()' is passed an incorrect value for its 'len' argument.
