Details

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 cachepeer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peerdigest.cc mishandles EOF.
