CVE-2020-24606
8.6
CVSS:3.1/AC:L/AV:N/A:H/C:N/I:N/PR:N/S:C/UI:N
Summary
Squid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF.
