CWEhttps://cwe.mitre.org/data/definitions/674.html

url::recvline in url.cpp in libproxy 0.4.x through 0.4.15 allows a remote HTTP server to trigger uncontrolled recursion via a response composed of an infinite stream that lacks a newline character. This leads to stack exhaustion.

Weakness

The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
