Severity: Low Date : 2020-12-05 CVE-ID : CVE-2020-25219 Package : libproxy Type : denial of service Remote : Yes Link : https://security.archlinux.org/AVG-1226
The package libproxy before version 0.4.16-1 is vulnerable to denial of service.
Upgrade to 0.4.16-1.
The problem has been fixed upstream in version 0.4.16.
url::recvline in url.cpp in libproxy 0.4.x through 0.4.15 allows a remote HTTP PAC server to trigger uncontrolled recursion via a response composed of an infinite stream that lacks a newline character. This leads to stack exhaustion.
A remote HTTP PAC server might be able to crash an application via a crafted response.
