{"id":"UBUNTU-CVE-2022-41318","details":"A buffer over-read was discovered in libntlmauth in Squid 2.5 through 5.6. Due to incorrect integer-overflow protection, the SSPI and SMB authentication helpers are vulnerable to reading unintended memory locations. In some configurations, cleartext credentials from these locations are sent to a client. This is fixed in 5.7.","modified":"2026-02-04T04:31:47.887654Z","published":"2022-09-23T00:00:00Z","related":["USN-5641-1","USN-6857-1"],"upstream":["CVE-2022-41318"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-41318"},{"type":"REPORT","url":"https://www.openwall.com/lists/oss-security/2022/09/23/2"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5641-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-41318"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6857-1"}],"affected":[{"package":{"name":"squid3","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/squid3@3.5.12-1ubuntu7.16+esm3?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.12-1ubuntu7.16+esm3"}]}],"versions":["3.3.8-1ubuntu16","3.3.8-1ubuntu17","3.5.12-1ubuntu6","3.5.12-1ubuntu7","3.5.12-1ubuntu7.1","3.5.12-1ubuntu7.2","3.5.12-1ubuntu7.3","3.5.12-1ubuntu7.4","3.5.12-1ubuntu7.5","3.5.12-1ubuntu7.6","3.5.12-1ubuntu7.7","3.5.12-1ubuntu7.8","3.5.12-1ubuntu7.9","3.5.12-1ubuntu7.10","3.5.12-1ubuntu7.11","3.5.12-1ubuntu7.12","3.5.12-1ubuntu7.13","3.5.12-1ubuntu7.14","3.5.12-1ubuntu7.15","3.5.12-1ubuntu7.16","3.5.12-1ubuntu7.16+esm1","3.5.12-1ubuntu7.16+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"squid","binary_version":"3.5.12-1ubuntu7.16+esm3"},{"binary_name":"squid-cgi","binary_version":"3.5.12-1ubuntu7.16+esm3"},{"binary_name":"squid-common","binary_version":"3.5.12-1ubuntu7.16+esm3"},{"binary_name":"squid-purge","binary_version":"3.5.12-1ubuntu7.16+esm3"},{"binary_name":"squid3","binary_version":"3.5.12-1ubuntu7.16+esm3"},{"binary_name":"squidclient","binary_version":"3.5.12-1ubuntu7.16+esm3"}],"availability":"Available
