{"schemaVersion":3,"id":"MGASA-2021-0196","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Updated krb5-appl packages fix security vulnerabilities\n\nAn issue was discovered in rcp in MIT krb5-appl through 1.0.3. Due to the rcp\nimplementation being derived from 1983 rcp, the server chooses which\nfiles/directories are sent to the client. However, the rcp client only\nperforms cursory validation of the object name returned (only directory\ntraversal attacks are prevented). A malicious rcp server (or\nMan-in-The-Middle attacker) can overwrite arbitrary files in the rcp client\ntarget directory. If recursive operation (-r) is performed, the server can\nmanipulate subdirectories as well (for example, to overwrite the\n.ssh/authorized_keys file). This issue is similar to CVE-2019-6111 and\nCVE-2019-7283 (CVE-2019-25017).\n\nIn the rcp client in MIT krb5-appl through 1.0.3 malicious servers could\nbypass intended access restrictions via the filename of . or an empty\nfilename, similar to CVE-2018-20685 and CVE-2019-7282. The impact is modifying\nthe permissions of the target directory on the client side (CVE-2019-25018).","dates":{"published":"2021-04-23T22:53:14.000Z","modified":"2026-04-16T04:40:38.584Z","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":"krb5-appl","name":"krb5-appl","label":"krb5-appl","ecosystem":"Mageia","cpePart":null,"purl":"pkg:rpm/mageia/krb5-appl","purlType":"rpm","versions":[{"text":"< 1.0.3-10.2.mga7","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 1.0.3-10.2.mga7","eol":null,"hubHref":null},{"vendor":"mageia","product":"krb5-appl","name":"krb5-appl","label":"krb5-appl","ecosystem":"Mageia","cpePart":null,"purl":"pkg:rpm/mageia/krb5-appl","purlType":"rpm","versions":[{"text":"< 1.0.3-13.1.mga8","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 1.0.3-13.1.mga8","eol":null,"hubHref":null}],"affectedCount":2,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://advisories.mageia.org/MGASA-2021-0196.html","label":"advisories.mageia.org/MGASA-2021-0196.html","hostname":"advisories.mageia.org","tags":["Advisory"]},{"url":"https://bugs.mageia.org/show_bug.cgi?id=28460","label":"bugs.mageia.org/show_bug.cgi?id=28460","hostname":"bugs.mageia.org","tags":["REPORT"]},{"url":"https://lists.suse.com/pipermail/sle-security-updates/2021-February/008353.html","label":"lists.suse.com/pipermail/sle-security-updates/2021-February/008353.html","hostname":"lists.suse.com","tags":["WEB"]}],"lineage":{"upstream":["CVE-2019-25017","CVE-2019-25018"],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2021-04-23T22:53:14.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-04-16T04:40:38.584Z","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":"2026-10-20T14:57:37.646Z","stale":false,"partial":false}}
