libproxy: uncontrolled recursion via an infinite stream response leading to stack exhaustion
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.
A flaw was found in libproxy in versions 0.4 through 0.4.15. A remote HTTP server can trigger an uncontrolled recursion via a response composed of an infinite stream that lacks a newline character leading to a stack exhaustion. The highest threat from this vulnerability is to system availability.
Statement: Red Hat has determined this flaw to be of moderate impact as the attack triggers an uncontrolled recursion beyond the attacker's control and results in a DoS, which

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is i
