{"id":"SUSE-SU-2018:3392-1","summary":"Security update for python-cryptography","details":"This update for python-cryptography fixes the following issues:\n\n- CVE-2018-10903: The finalize_with_tag API did not enforce a minimum tag\n  length. If a user did not validate the input length prior to passing it to\n  finalize_with_tag an attacker could craft an invalid payload with a shortened\n  tag (e.g. 1 byte) such that they would have a 1 in 256 chance of passing the\n  MAC check. GCM tag forgeries could have caused key leakage (bsc#1101820).\n","modified":"2026-03-11T07:00:30.572325Z","published":"2018-10-24T11:05:21Z","related":["CVE-2018-10903"],"upstream":["CVE-2018-10903"],"references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2018/suse-su-20183392-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1101820"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-10903"}],"affected":[{"package":{"name":"python-cryptography","ecosystem":"SUSE:Linux Enterprise Module for Basesystem 15","purl":"pkg:rpm/suse/python-cryptography&distro=SUSE%20Linux%20Enterprise%20Module%20for%20Basesystem%2015"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.4-4.3.1"}]}],"ecosystem_specific":{"binaries":[{"python2-cryptography":"2.1.4-4.3.1","python3-cryptography":"2.1.4-4.3.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2018:3392-1.json"}}],"schema_version":"1.7.5"}
