https://bugzilla.suse.com/show_bug.cgi?id=1222461 Bug ID: 1222461 Summary: VUL-0: CVE-2024-22189: TRACKERBUG: quic-go: memory exhaustion attack against QUIC's connection ID mechanism Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.6 Hardware: Other URL: https://smash.suse.de/issue/400376/ OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Security Assignee: security-team@suse.de Reporter: smash_bz@suse.de QA Contact: security-team@suse.de CC: camila.matos@suse.com Target Milestone: --- Found By: Security Response Team Blocker: --- 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.
