An\nattacker who supplies a crafted file to an application linked with BFD, and\nusing the DWARF functionality, could cause an impact to system availability\nby way of excessive memory consumption (CVE-2021-3487).\n\nThere is an open race window when writing output in the following utilities\nin GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When\nthese utilities are run as a privileged user (presumably as part of a script\nupdating binaries across different users), an unprivileged user can trick\nthese utilities into getting ownership of arbitrary files through a symlink\n(CVE-2021-20197).\n\nFor more info about the 2.36 update, see the sourceware link.","dates":{"published":"2021-07-12T20:26:21.000Z","modified":"2026-04-16T04:43:28.977Z","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":"binutils","name":"binutils","label":"binutils","ecosystem":"Mageia","cpePart":null,"purl":"pkg:rpm/mageia/binutils","purlType":"rpm","versions":[{"text":"< 2.36.1-1.1.mga8","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 2.36.1-1.1.mga8","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://advisories.mageia.org/MGASA-2021-0341.html","label":"advisories.mageia.org/MGASA-2021-0341.html","hostname":"advisories.mageia.org","tags":["Advisory"]},{"url":"https://bugs.mageia.org/show_bug.cgi?id=28305","label":"bugs.mageia.org/show_bug.cgi?id=28305","hostname":"bugs.mageia.org","tags":["REPORT"]},{"url":"https://sourceware.org/pipermail/binutils/2021-January/115071.html","label":"sourceware.org/pipermail/binutils/2021-January/115071.html","hostname":"sourceware.org","tags":["WEB"]}],"lineage":{"upstream":["CVE-2021-20197","CVE-2021-3487"],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2021-07-12T20:26:21.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-04-16T04:43:28.977Z","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":"2026-10-20T16:38:07.421Z","stale":false,"partial":false}}
