{"id":"GHSA-8477-3v39-ggpm","summary":"Improper Validation of Integrity Check Value in Bouncy Castle","details":"The default BKS keystore use an HMAC that is only 16 bits long, which can allow an attacker to compromise the integrity of a BKS keystore. Bouncy Castle release 1.47 changes the BKS format to a format which uses a 160 bit HMAC instead. This applies to any BKS keystore generated prior to BC 1.47. For situations where people need to create the files for legacy reasons a specific keystore type \"BKS-V1\" was introduced in 1.49. It should be noted that the use of \"BKS-V1\" is discouraged by the library authors and should only be used where it is otherwise safe to do so, as in where the use of a 16 bit checksum for the file integrity check is not going to cause a security issue in itself.","aliases":["CVE-2018-5382"],"modified":"2023-11-08T04:00:20.719699Z","published":"2022-05-13T01:01:01Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2022-06-28T23:51:50Z","nvd_published_at":"2018-04-16T14:29:00Z","cwe_ids":["CWE-354"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-5382"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2018:2927"},{"type":"WEB","url":"https://www.bouncycastle.org/releasenotes.html"},{"type":"WEB","url":"https://www.kb.cert.org/vuls/id/306792"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuoct2020.html"},{"type":"WEB","url":"http://www.securityfocus.com/bid/103453"}],"affected":[{"package":{"name":"org.bouncycastle:bcprov-jdk15on","ecosystem":"Maven","purl":"pkg:maven/org.bouncycastle/bcprov-jdk15on"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.50"}]}],"versions":["1.46","1.47","1.48","1.49"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-8477-3v39-ggpm/GHSA-8477-3v39-ggpm.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"}]}
