Last modified: 2022-10-16 16:28:01 UTC
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-31806 Due to an incorrect input validation bug Squid is vulnerable to a Denial of Service attack against all clients using the proxy. http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-31807 Due to an incorrect memory management bug Squid is vulnerable to a Denial of Service attack against all clients using the proxy. http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-31808 Due to an integer overflow bug Squid is vulnerable to a Denial of Service attack against all clients using the proxy. Severity: These problems all allow a trusted client to perform Denial of Service when making HTTP Range requests. The integer overflow problem allows a remote server to perform Denial of Service when delivering responses to HTTP Range requests. The issue trigger is a header which can be expected to exist in HTTP traffic without any malicious intent.
