https://bugzilla.suse.com/show_bug.cgi?id=1222468 Bug ID: 1222468 Summary: VUL-0: CVE-2024-22189: caddy: quic-go: memory exhaustion attack against QUIC's connection ID mechanism Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other URL: https://smash.suse.de/issue/400376/ OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Security Assignee: alexandre.vicenzi@suse.com Reporter: camila.matos@suse.com QA Contact: qa-bugs@suse.de CC: camila.matos@suse.com, jkowalczyk@suse.com, security-team@suse.de, smash_bz@suse.de Blocks: 1222461 Target Milestone: --- Found By: Security Response Team Blocker: --- +++ This bug was initially created as a clone of Bug #1222461 +++ quic-go is an implementation of the QUIC protocol in Go. Prior to version 0.42.0, an attacker can cause its peer to run out of memory sending a large number of `NEW_CONNECTION_ID` frames that retire old connection IDs. The receiver is supposed to respond to each retirement frame with a `RETIRE_CONNECTION_ID` frame. The attacker can prevent the receiver from sending out (the vast majority of) these `RETIRE_CONNECTION_ID` frames by collapsing the peers congestion window (by selectively acknowledging received packets) and by manipulating the peer's RTT estimate. Version 0.42.0 contains a patch for the issue. No known workarounds are available.
