CVE-2020-25219 is a high-severity vulnerability affecting libproxy versions 0.4.x through 0.4.15, impacting products from Canonical, Debian, Fedora, and openSUSE. A remote HTTP server can exploit this flaw by sending an infinite stream without a newline character, causing uncontrolled recursion and leading to stack exhaustion. This attack requires no user interaction and has a high impact on availability, but there is no evidence of active exploitation, public exploit code, or significant community discussion.
