medium Nessus Plugin ID 190826

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 39 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2024-c46536abe6 advisory.

 - quic-go is an implementation of the QUIC protocol (RFC 9000, RFC 9001, RFC 9002) in Go. An attacker can cause its peer to run out of memory sending a large number of PATH_CHALLENGE frames. The receiver is supposed to respond to each PATH_CHALLENGE frame with a PATH_RESPONSE frame. The attacker can prevent the receiver from sending out (the vast majority of) these PATH_RESPONSE frames by collapsing the peers congestion window (by selectively acknowledging received packets) and by manipulating the peer's RTT estimate. This vulnerability has been patched in versions 0.37.7, 0.38.2 and 0.39.4. (CVE-2023-49295)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected syncthing package.
