Affected Packages:

libproxy

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2020-25219.

More information:

It was discovered that there was a denial of service attack in libproxy, a library to make applications HTTP proxy aware. A remote server could cause an infinite stack recursion.

• CVE-2020-25219

  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.

For Debian 9 Stretch, these problems have been fixed in version 0.4.14-2+deb9u1.

We recommend that you upgrade your libproxy packages.
