Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process.","published":"2020-10-01T20:15:13.033Z","modified":"2026-10-10T02:45:18.019152814Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.ant:ant","fixedVersion":"1.10.9"}],"fix":{"url":"https://github.com/apache/ant/commit/87ac51d3c22bcf7cfd0dc07cb0bd04a496e0d428","label":"apache/ant@87ac51d"},"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/r107ea1b1a7a214bc72fe1a04207546ccef542146ae22952e1013b5cc%40%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r1dc8518dc99c42ecca5ff82d0d2de64cd5d3a4fa691eb9ee0304781e%40%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r2306b67f20c24942b872b0a41fbdc9330e8467388158bcd19c1094e0%40%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r4ca33fad3fb39d130cda287d5a60727d9e706e6f2cf2339b95729490%40%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r5e1cdd79f019162f76414708b2092acad0a6703d666d72d717319305%40%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/raaeddc41da8f3afb1cb224876084a45f68e437a0afd9889a707e4b0c%40%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rbfe9ba28b74f39f46ec1bbbac3bef313f35017cf3aac13841a84483a%40%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AALW42FWNQ35F7KB3JVRC6NBVV7AAYYI/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DYBRN5C2RW7JRY75IB7Q7ZVKZCHWAQWS/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/U3NRQQ7ECII4ZNGW7GBC225LVYMPQEKB/"},{"type":"ADVISORY","url":"https://github.com/gradle/gradle/security/advisories/GHSA-j45w-qrgf-25vm"},{"type":"ADVISORY","url":"https://lists.apache.org/thread.html/rc3c8ef9724b5b1e171529b47f4b35cb7920edfb6e917fa21eb6c64ea%40%3Cdev.ant.apache.org%3E"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202011-18"},{"type":"FIX","url":"https://www.oracle.com//security-alerts/cpujul2021.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuApr2021.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuapr2022.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpujan2021.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpujan2022.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuoct2021.html"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-11979"},{"type":"WEB","url":"https://github.com/apache/ant/commit/87ac51d3c22bcf7cfd0dc07cb0bd04a496e0d428"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/U3NRQQ7ECII4ZNGW7GBC225LVYMPQEKB"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/DYBRN5C2RW7JRY75IB7Q7ZVKZCHWAQWS"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/AALW42FWNQ35F7KB3JVRC6NBVV7AAYYI"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rbfe9ba28b74f39f46ec1bbbac3bef313f35017cf3aac13841a84483a@%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/raaeddc41da8f3afb1cb224876084a45f68e437a0afd9889a707e4b0c@%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r5e1cdd79f019162f76414708b2092acad0a6703d666d72d717319305@%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r4ca33fad3fb39d130cda287d5a60727d9e706e6f2cf2339b95729490@%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r2306b67f20c24942b872b0a41fbdc9330e8467388158bcd19c1094e0@%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r1dc8518dc99c42ecca5ff82d0d2de64cd5d3a4fa691eb9ee0304781e@%3Cdev.creadur.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r107ea1b1a7a214bc72fe1a04207546ccef542146ae22952e1013b5cc@%3Cdev.creadur.apache.org%3E"},{"type":"PACKAGE","url":"https://github.com/apache/ant"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-10T02:45:18.019152814Z"}}
