When Squid is configured to use Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as domain, uri, and qop. Squid checks if this token's value starts with a quote and ends with one. If so, it performs a memcpy of its length minus 2. Squid never checks whether the value is just a single quote (which would satisfy its requirements), leading to a memcpy of its length minus 1.","severity":{"version":"3.1","score":9.8,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","level":"critical","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-10","score":0.24401,"percentile":0.97886,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-119","CWE-787"],"published":"2019-07-11T00:00:00Z","modified":"2026-10-29T11:00:18Z","fixes":[{"ecosystem":"Alpine:v3.10","package":"squid","fixed_in":["4.8-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.9","package":"squid","fixed_in":["4.8-r0"],"sources":["osv"]},{"ecosystem":"Debian:12","package":"squid","fixed_in":["4.8-1"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"squid","fixed_in":["4.8-1"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"squid","fixed_in":["4.8-1"],"sources":["osv"]},{"ecosystem":"Ubuntu:16.04:LTS","package":"squid3","fixed_in":["3.5.12-1ubuntu7.8"],"sources":["osv"]},{"ecosystem":"Ubuntu:18.04:LTS","package":"squid3","fixed_in":["3.5.27-1ubuntu1.3"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Alpine:v3.10","package":"squid","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.3.9"},{"fixed":"4.8-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.9","package":"squid","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.3.9"},{"fixed":"4.8-r0"}]}]},{"source":"osv","ecosystem":"AlmaLinux:8","package":"libecap","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.1-2.module_el8.6.0+2741+01592ae8"}]}],"bundled":3},{"source":"osv","ecosystem":"AlmaLinux:8","package":"libecap-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.1-2.module_el8.6.0+2741+01592ae8"}]}],"bundled":3},{"source":"osv","ecosystem":"TuxCare:OracleLinux:6","package":"squid34","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7:3.4.14-16.el6.tuxcare.els13"}]}],"bundled":12},{"source":"osv","ecosystem":"TuxCare:CentOS:6","package":"squid34","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7:3.4.14-16.el6.tuxcare.els13"}]}],"bundled":12},{"source":"osv","ecosystem":"Debian:12","package":"squid","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.8-1"}]}]},{"source":"osv","ecosystem":"Debian:13","package":"squid","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.8-1"}]}]},{"source":"osv","ecosystem":"Debian:14","package":"squid","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.8-1"}]}]},{"source":"osv","ecosystem":"Debian:8","package":"squid3","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.8-6+deb8u8"}]}],"versions":["3.4.8-6","3.4.8-6+deb8u1","3.4.8-6+deb8u2","3.4.8-6+deb8u2~bpo70+1","3.4.8-6+deb8u3","3.4.8-6+deb8u4","3.4.8-6+deb8u5","3.4.8-6+deb8u6","3.4.8-6+deb8u7"],"bundled":2},{"source":"osv","ecosystem":"Debian:9","package":"squid3","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.23-5+deb9u2"}]}],"versions":["3.5.23-5","3.5.23-5+deb9u1"],"bundled":19},{"source":"osv","ecosystem":"Debian:10","package":"squid","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.6-1+deb10u1"}]}],"versions":["4.6-1"],"bundled":5},{"source":"osv","ecosystem":"Mageia:6","package":"squid","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.27-1.2.mga6"}]}],"bundled":3},{"source":"osv","ecosystem":"Mageia:7","package":"squid","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.8-1.mga7"}]}],"bundled":5},{"source":"osv","ecosystem":"Red

When Squid is configured to use Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as domain, uri, and qop. Squid checks if this token's value starts with a quote and ends with one. If so, it performs a memcpy of its length minus 2. Squid never checks whether the value is just a single quote (which would satisfy its requirements), leading to a memcpy of its length minus 1.","status":"published","published":"2019-07-11T00:00:00Z","modified":"2026-02-04T04:15:58.122248Z","cvss":[{"version":"3.1","score":9.8,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","level":"critical"},{"version":"3.0","score":9.8,"vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","level":"critical"}],"updated_at":"2026-11-02T15:54:19.202697Z"},{"id":"ALSA-2020:2041","title":"Important: squid:4 security update","description":"Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects.\n\nSecurity Fix(es):\n\n* squid: improper check for new member in ESIExpression::Evaluate allows for stack buffer overflow (CVE-2019-12519)\n\n* squid: improper access restriction upon Digest Authentication nonce replay could lead to remote code execution (CVE-2020-11945)\n\n* squid: parsing of header Proxy-Authentication leads to memory corruption (CVE-2019-12525)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.","status":"published","published":"2020-05-06T12:52:10Z","modified":"2026-10-29T11:00:18.787433548Z","updated_at":"2026-11-02T15:27:51.196609Z"},{"id":"CLSA-2026-1777539404","title":"squid34: Fix of 12 CVEs","description":"- CVE-2019-12525: fix heap buffer over-read in Digest auth parameter parsing\n- CVE-2018-1000027: fix NULL pointer dereference in X-Forwarded-For logging for internal transactions\n- CVE-2018-19131: escape certificate field injection via %D in ERR_SECURE_CONNECT_FAIL page\n- CVE-2018-19132: fix memory leak when parsing denied or malformed SNMP packets\n- CVE-2019-13345: escape user_name and pub_auth parameters in cachemgr.cgi to prevent reflected XSS\n- CVE-2019-18860: validate hostname parameter in cachemgr.cgi to prevent reflected XSS\n- CVE-2019-18677: prevent hostname truncation when append_domain expands origin-relative domains\n- CVE-2019-18679: remove in-memory pointer from Digest nonce hash input (ASLR bypass)\n- CVE-2019-18678: reject HTTP requests with BWS between header field-name and colon (RFC 7230 3.2.4)\n- CVE-2019-12523: validate URN NID per RFC 8141 to prevent SSRF via crafted urn: requests\n- CVE-2019-12528: track FTP listing token positions to avoid strstr-based over-read into adjacent heap\n- CVE-2019-12529: replace uudecode with base64_decode in Basic auth to bound input-buffer reads","status":"published","published":"2026-04-30T08:56:49Z","modified":"2026-10-21T10:48:12.180143482Z","updated_at":"2026-11-02T15:43:44.384419Z"},{"id":"CLSA-2026-1777541147","title":"squid34: Fix of 12 CVEs","description":"- CVE-2019-12525: fix heap buffer over-read in Digest auth parameter parsing\n- CVE-2018-1000027: fix NULL pointer dereference in X-Forwarded-For logging for internal transactions\n- CVE-2018-19131: escape certificate field injection via %D in ERR_SECURE_CONNECT_FAIL page\n- CVE-2018-19132: fix memory leak when parsing denied or malformed SNMP packets\n- CVE-2019-13345: escape user_name and pub_auth parameters in cachemgr.cgi to prevent reflected XSS\n- CVE-2019-18860: validate hostname parameter in cachemgr.cgi to prevent reflected XSS\n- CVE-2019-18677: prevent hostname truncation when append_domain expands origin-relative domains\n- CVE-2019-18679: remove in-memory pointer from Digest nonce hash input (ASLR bypass)\n- CVE-2019-18678: reject HTTP requests with BWS between header field-name and colon (RFC 7230 3.2.4)\n- CVE-2019-12523: validate URN NID per RFC 8141 to prevent SSRF via crafted urn: requests\n- CVE-2019-12528: track FTP listing token positions to avoid strstr-based over-read into adjacent heap\n- CVE-2019-12529: replace uudecode with base64_decode in Basic auth to bound input-buffer reads","status":"published","published":"2026-05-02T01:02:36Z","modified":"2026-10-21T10:47:49.998050891Z","updated_at":"2026-11-02T15:43:44.384419Z"},{"id":"DLA-1858-1","title":"squid3 -
