Summary
squid security update
Details

Squid is a high-performance proxy caching server. It handles all requests in a single, non-blocking, I/O-driven process and keeps meta data and implements negative caching of failed requests.

Security Fix(es):

Description: Due to chunked decoder lenience Squid is vulnerable to Request/Response smuggling attacks when parsing HTTP/1.1 and ICAP messages

Reference: https://github.com/squid-cache/squid/security/advisories/GHSA-j83v-w3p4-5cqh

Affected versions: 2.6-6.3. Patched in 6.4.(CVE-2023-46846)

Description: Due to a buffer overflow bug Squid is vulnerable to a Denial of Service attack against HTTP Digest Authentication

Reference: https://github.com/squid-cache/squid/security/advisories/GHSA-phqj-m8gv-cq4g

Affected versions: 3.2.0.1-5.9, 6.0-6.3(CVE-2023-46847)

Severity
9.9 (Critical)
