{"id":"MGASA-2015-0485","summary":"Updated proftpd packages fix security vulnerabilities","details":"Updated proftpd packages fix security vulnerability:\n\nPart of the SFTP handshake involves \"extensions\", which are key/value pairs,\ncomprised of strings. In SSH, strings are encoded for network transport as a\n32-bit length, followed by the bytes. The mod_sftp module currently places no\nbounds/length limitations when reading these SFTP extension key/value data from\nthe network. A malicious attacker might attempt to encode large values, and\nallocate more memory than is necessary, causing excessive resource usage or the\nFTP daemon to crash (proftpd#4210).\n\nThis update also includes a fix for a crash in mod_lang (proftpd#4206).\n","modified":"2026-04-16T04:27:56.041365Z","published":"2015-12-24T11:08:20Z","references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2015-0485.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=17336"},{"type":"REPORT","url":"http://bugs.proftpd.org/show_bug.cgi?id=4206"},{"type":"REPORT","url":"http://bugs.proftpd.org/show_bug.cgi?id=4210"},{"type":"WEB","url":"https://lists.fedoraproject.org/pipermail/package-announce/2015-November/171090.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/pipermail/package-announce/2015-December/173656.html"}],"affected":[{"package":{"name":"proftpd","ecosystem":"Mageia:5","purl":"pkg:rpm/mageia/proftpd?arch=source&distro=mageia-5"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.5-5.1.mga5"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2015-0485.json"}}],"schema_version":"1.7.5","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
