NVD Description

package and not the squid:4/libecap
package as distributed by AlmaLinux
.
See How to fix?
for AlmaLinux:8
relevant fixed versions and status.
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.
