This is due to an upstream issue with python's SSL module rather than directly with libcloud.","published":"2011-09-12T12:41:27Z","modified":"2026-04-10T03:41:30.689895Z","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":{"score":0.0139,"percentile":0.69913,"asOf":"2026-08-14"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"apache-libcloud","fixedVersion":"0.4.0"}],"fix":{"url":"https://github.com/apache/libcloud/commit/87ee61e6ba03a43dcefea2ce180988bec066b6fd","label":"apache/libcloud@87ee61e"},"references":[{"type":"WEB","url":"http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=598463"},{"type":"WEB","url":"http://mail-archives.apache.org/mod_mbox/incubator-libcloud/201009.mbox/%3C5860913.463891285776633273.JavaMail.jira%40thor%3E"},{"type":"WEB","url":"http://mail-archives.apache.org/mod_mbox/incubator-libcloud/201011.mbox/browser"},{"type":"WEB","url":"http://wiki.apache.org/incubator/LibcloudSSL"},{"type":"WEB","url":"https://issues.apache.org/jira/browse/LIBCLOUD-55"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2010-4340"},{"type":"WEB","url":"https://github.com/apache/libcloud/commit/87ee61e6ba03a43dcefea2ce180988bec066b6fd"},{"type":"WEB","url":"https://bugs.python.org/issue1589"},{"type":"PACKAGE","url":"https://github.com/apache/libcloud"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/apache-libcloud/PYSEC-2011-24.yaml"},{"type":"WEB","url":"http://mail-archives.apache.org/mod_mbox/incubator-libcloud/201009.mbox/%3C5860913.463891285776633273.JavaMail.jira@thor%3E"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-04-10T03:41:30.689895Z"}}
