{"id":"ALPINE-CVE-2019-12525","details":"An issue was discovered in Squid 3.3.9 through 3.5.28 and 4.x through 4.7. 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.","modified":"2026-09-10T06:17:54.456828758Z","published":"2019-07-11T19:15:13Z","upstream":["CVE-2019-12525"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2019-12525"}],"affected":[{"package":{"name":"squid","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.3.9"},{"fixed":"4.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12525.json"}},{"package":{"name":"squid","ecosystem":"Alpine:v3.9","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.3.9"},{"fixed":"4.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12525.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
