CWE ID 400
Summary
CVE-2023-6193 affects quiche version 0.15.0 through 0.19.0, where an attacker can manipulate QUIC path validation messages, causing an unbounded queueing of PATH_RESPONSE frames. This results in excessive resource consumption as the recipient is forced to send responses at a slower rate than they are received. The vulnerability arises due to the lack of proper handling of PATH_CHALLENGE frames, leading to QUIC connections becoming congested. Versions of quiche greater than 0.19.0 have addressed this issue.
