{"schemaVersion":3,"id":"MGASA-2018-0494","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Updated keepalived package fixes security vulnerabilities\n\nkeepalived before version 2.0.9 didn't check for pathnames with symlinks\nwhen writing data to a temporary file upon a call to PrintData or\nPrintStats. This allowed local users to overwrite arbitrary files if\nfs.protected_symlinks is set to 0, as demonstrated by a symlink from\n/tmp/keepalived.data or /tmp/keepalived.stats to /etc/passwd\n(CVE-2018-19044).\n\nkeepalived before version 2.0.9 used mode 0666 when creating new\ntemporary files upon a call to PrintData or PrintStats, potentially\nleaking sensitive information (CVE-2018-19045).\n\nkeepalived before version 2.0.10 didn't check for existing plain files\nwhen writing data to a temporary file upon a call to PrintData or\nPrintStats. If a local attacker had previously created a file with the\nexpected name (e.g., /tmp/keepalived.data or /tmp/keepalived.stats),\nwith read access for the attacker and write access for the keepalived\nprocess, then this potentially leaked sensitive information\n(CVE-2018-19046).\n\nkeepalived before version 2.0.9 has a heap-based buffer overflow when\nparsing HTTP status codes resulting in DoS or possibly unspecified other\nimpact, because extract_status_code in lib/html.c has no validation of\nthe status code and instead writes an unlimited amount of data to the\nheap (CVE-2018-19115).","dates":{"published":"2018-12-29T23:24:32.000Z","modified":"2026-04-16T06:26:24.398Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"mageia","product":"keepalived","name":"keepalived","label":"keepalived","ecosystem":"Mageia","cpePart":null,"purl":"pkg:rpm/mageia/keepalived","purlType":"rpm","versions":[{"text":"< 2.0.10-1.mga6","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 2.0.10-1.mga6","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://advisories.mageia.org/MGASA-2018-0494.html","label":"advisories.mageia.org/MGASA-2018-0494.html","hostname":"advisories.mageia.org","tags":["Advisory"]},{"url":"https://bugs.mageia.org/show_bug.cgi?id=24063","label":"bugs.mageia.org/show_bug.cgi?id=24063","hostname":"bugs.mageia.org","tags":["REPORT"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/6YQ7NS6S7B7V2X5NEUJKMTNXL3YPD7H3/","label":"lists.fedoraproject.org/archives/…","hostname":"lists.fedoraproject.org","tags":["WEB"]}],"lineage":{"upstream":["CVE-2018-19044","CVE-2018-19045","CVE-2018-19046","CVE-2018-19115"],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2018-12-29T23:24:32.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-04-16T06:26:24.398Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-19T22:26:05.845Z","stale":false,"partial":false}}
