CVE-2020-24606

7.5 highEPSS 5.0%

High (7.5). EPSS 5.0% chance of exploitation in the next 30 days.

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.
