Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

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.
