Description Dhananjay Arunesh 2019-07-17 03:55:45 UTC 
A vulnerability was found in squid before 4.8, due to incorrect string termination the cachemgr.cgi may access unallocated memory. On systems with memory access protections this can result in the CGI process terminating unexpectedly. Resulting in a denial of service for all clients using it.
