{"id":"MGASA-2016-0208","summary":"Updated botan packages fix security vulnerabilities","details":"Updated botan packages fix security vulnerabilities:\n\nDuring RSA decryption, how long decoding of PKCS #1 v1.5 padding took was\ninput dependent. If these differences could be measured by an attacker,\nit could be used to mount a Bleichenbacher million-message attack\n(CVE-2015-7827).\n\nECDSA (and DSA) signature algorithms perform a modular inverse on the\nsignature nonce k. The modular inverse algorithm used had input dependent\nloops, and it is possible a side channel attack could recover sufficient\ninformation about the nonce to eventually recover the ECDSA secret key\n(CVE-2016-2849).\n","modified":"2026-04-16T01:46:31.246971450Z","published":"2016-05-29T13:55:26Z","upstream":["CVE-2015-7827","CVE-2016-2849"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2016-0208.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=18356"},{"type":"WEB","url":"https://botan.randombit.net/security.html"},{"type":"WEB","url":"https://www.debian.org/security/2016/dsa-3565"}],"affected":[{"package":{"name":"botan","ecosystem":"Mageia:5","purl":"pkg:rpm/mageia/botan?arch=source&distro=mageia-5"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.10.12-1.1.mga5"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2016-0208.json"}}],"schema_version":"1.7.5","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
