{"id":"CVE-2021-35940","details":"An out-of-bounds array read in the apr_time_exp*() functions was fixed in the Apache Portable Runtime 1.6.3 release (CVE-2017-12613). The fix for this issue was not carried forward to the APR 1.7.x branch, and hence version 1.7.0 regressed compared to 1.6.3 and is vulnerable to the same issue.","aliases":["BIT-apr-2021-35940"],"modified":"2026-04-16T04:34:40.921441583Z","published":"2021-08-23T10:15:07.230Z","related":["openSUSE-SU-2024:11865-1"],"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/r7bb4a6ed88fc48152174e664aae30ea9a8b058eb5b44cf08cb9beb4b%40%3Cdev.apr.apache.org%3E"},{"type":"WEB","url":"http://mail-archives.apache.org/mod_mbox/www-announce/201710.mbox/%3CCACsi251B8UaLvM-rrH9fv57-zWi0zhyF3275_jPg1a9VEVVoxw%40mail.gmail.com%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r1c788464a25fbc046a72aff451bc8186386315d92a2dd0349903fa4f%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r54c755c74b9e3846cfd84039b1967d37d2870750a02d7c603983f6ed%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r7bb4a6ed88fc48152174e664aae30ea9a8b058eb5b44cf08cb9beb4b%40%3Cdev.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rafe54755850e93de287c36540972457b2dd86332106aa7817c7c27fb%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r317c398ee5736e627f7887b06607e5c58b45a696d352ba8c14615f55%40%3Cdev.apr.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r72479f4dcffaa8a4732d5a0e87fecc4bace4932e28fc26f7d400e2b3%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r72a069753b9363c29732e59ad8f0d22a633fb6a699980407511ac961%40%3Cdev.apr.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/ra38094406cc38a05218ebd1158187feda021b0c3a1df400bbf296af8%40%3Cdev.apr.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rb1f3c85f50fbd924a0051675118d1609e57957a02ece7facb723155b%40%3Cannounce.apache.org%3E"},{"type":"ADVISORY","url":"https://lists.apache.org/thread.html/ra2868b53339a6af65577146ad87016368c138388b09bff9d2860f50e%40%3Cdev.apr.apache.org%3E"},{"type":"ADVISORY","url":"http://svn.apache.org/viewvc?view=revision&revision=1891198"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2021/08/23/1"},{"type":"FIX","url":"https://dist.apache.org/repos/dist/release/apr/patches/apr-1.7.0-CVE-2021-35940.patch"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpujul2022.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/apr","events":[{"introduced":"0"},{"last_affected":"74084e43adbf6b9df152a8b5d051b8180ebc1a69"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"1.7.0"}]}}],"versions":["1.7.0"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"12.2.1.3.0"}]},{"events":[{"introduced":"0"},{"last_affected":"12.2.1.4.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-35940.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H"}]}
