{"id":"UBUNTU-CVE-2026-85532","details":"Apache WSS4J accepted attacker-controlled derived-key lengths and offsets without adequate bounds. This could permit cryptographically weak keys or excessive CPU and memory consumption when processing crafted WS-Security messages. The fixes enforce a minimum key length of 16 bytes, a maximum length of 512 bytes, and a maximum offset of 4096 bytes. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.","modified":"2026-10-08T09:47:51Z","published":"2026-09-30T12:17:00Z","upstream":["CVE-2026-85532"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-85532"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-85532"},{"type":"REPORT","url":"https://lists.apache.org/thread.html/7jllcpbf4nbzhdp2vchz5yplnl5w6vd6"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2026/09/30/8"}],"affected":[{"package":{"name":"wss4j","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/wss4j?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.15-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.6.15-2","binary_name":"libwss4j-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-85532.json"}},{"package":{"name":"wss4j","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/wss4j?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.19-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libwss4j-java","binary_version":"1.6.19-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-85532.json"}},{"package":{"name":"wss4j","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/wss4j?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.19-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libwss4j-java","binary_version":"1.6.19-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-85532.json"}},{"package":{"name":"wss4j","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/wss4j?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.19-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.6.19-2","binary_name":"libwss4j-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-85532.json"}},{"package":{"name":"wss4j","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/wss4j?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.19-3"],"ecosystem_specific":{"binaries":[{"binary_name":"libwss4j-java","binary_version":"1.6.19-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-85532.json"}},{"package":{"name":"wss4j","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/wss4j?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.19-4","1.6.19-4build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libwss4j-java","binary_version":"1.6.19-4build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-85532.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:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
