An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a
buffer-management bug, it allows a denial of service. When resolving a
request with the urn: scheme, the parser leaks a small amount of memory.
However, there is an unspecified attack methodology that can easily trigger
a large amount of memory consumption.

: Yes\nLink : https://security.archlinux.org/AVG-1949\n\nSummary\n=======\n\nThe package squid before version 4.15-1 is vulnerable to denial of\nservice.\n\nResolution\n==========\n\nUpgrade to 4.15-1.\n\n# pacman -Syu \"squid>=4.15-1\"\n\nThe problems have been fixed upstream in version 4.15.\n\nWorkaround\n==========\n\n- CVE-2021-28651 can be mitigated by disabling URN processing by the\nproxy, by adding these lines to squid.conf:\n\nacl URN proto URN\nhttp_access deny URN\n\n- CVE-2021-28652 can be mitigated by either disabling Cache Manager\naccess entirely if not needed, by placing the following line in\nsquid.conf before lines containing \"allow\":\n\nhttp_access deny manager\n\nor by hardening Cache Manager access privileges, for example: require\nauthentication or other access controls in http_access beyond the\ndefault IP address restriction.\n\n- No known mitigations exist for CVE-2021-28662.\n\nDescription\n===========\n\n- CVE-2021-28651 (denial of service)\n\nDue to a buffer management bug Squid before version 4.15 is vulnerable\nto a denial of service attack against the server it is operating on.\nThis attack is limited to proxies which attempt to resolve a \"urn:\"\nresource identifier. Support for this resolving is enabled by default\nin all Squid.\n\n- CVE-2021-28652 (denial of service)\n\nDue to an incorrect parser validation bug Squid before version 4.15 is\nvulnerable to a denial of Service attack against the Cache Manager API.\n\n- CVE-2021-28662 (denial of service)\n\nDue to an input validation bug Squid before version 4.15 is vulnerable\nto a denial of service against all clients using the proxy.\n\nImpact\n======\n\nA remote attacker can cause denial of service through crafted requests.\n\nReferences\n==========\n\nhttps://github.com/squid-cache/squid/security/advisories/GHSA-ch36-9jhx-phm4\nhttp://www.squid-cache.org/Versions/v4/changesets/squid-4-a975fd5aedc866629214aaaccb38376855351899.patch\nhttps://github.com/squid-cache/squid/security/advisories/GHSA-m47m-9hvw-7447\nhttp://www.squid-cache.org/Versions/v4/changesets/squid-4-0003e3518dc95e4b5ab46b5140af79b22253048e.patch\nhttps://github.com/squid-cache/squid/security/advisories/GHSA-jjq6-mh2h-g39h\nhttp://www.squid-cache.org/Versions/v4/changesets/squid-4-b1c37c9e7b30d0efb5e5ccf8200f2a646b9c36f8.patch\nhttps://security.archlinux.org/CVE-2021-28651\nhttps://security.archlinux.org/CVE-2021-28652\nhttps://security.archlinux.org/CVE-2021-28662", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "NONE", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "NONE", "baseScore": 7.5, "privilegesRequired": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "userInteraction": "NONE", "version": "3.1"}, "impactScore": 3.6}, "published": "2021-05-19T00:00:00", "type": "archlinux", "title": "[ASA-202105-10] squid: denial of service", "bulletinFamily": "unix", "cvss2": {"severity": "MEDIUM", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "NONE", "availabilityImpact": "PARTIAL", "integrityImpact": "NONE", "baseScore": 5.0, "vectorString": "AV:N/AC:L/Au:N/C:N/I:N/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "acInsufInfo": false, "impactScore": 2.9, "obtainUserPrivilege": false}, "cvelist": ["CVE-2021-28651", "CVE-2021-28652", "CVE-2021-28662"], "modified": "2021-05-19T00:00:00", "id": "ASA-202105-10", "href": "https://security.archlinux.org/ASA-202105-10", "cvss": {"score": 5.0, "vector": "AV:N/AC:L/Au:N/C:N/I:N/A:P"}}], "suse": [{"lastseen": "2022-11-08T04:09:03", "description": "An update that solves 5 vulnerabilities and has three fixes\n is now available.\n\nDescription:\n\n This update for squid fixes the following issues:\n\n -
