{"id":"GHSA-2rcm-phc9-3945","summary":"Pyopenssl Incorrect Memory Management","details":"It was discovered that pyOpenSSL incorrectly handled memory when performing operations on a PKCS #12 store. A remote attacker could possibly use this issue to cause pyOpenSSL to consume resources, resulting in a denial of service.\n\nThis attack appear to be exploitable via Depends upon calling application, however it could be as simple as initiating a TLS connection that would cause the calling application to reload certificates from a PKCS #12 store. This vulnerability appears to have been fixed in 17.5.0.","aliases":["CVE-2018-1000808","PYSEC-2018-24"],"modified":"2024-10-21T21:23:52.139218Z","published":"2018-10-10T16:10:23Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2020-06-16T20:52:58Z","nvd_published_at":"2018-10-08T15:29:00Z","cwe_ids":["CWE-401","CWE-404"],"severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-1000808"},{"type":"WEB","url":"https://github.com/pyca/pyopenssl/pull/723"},{"type":"WEB","url":"https://github.com/pyca/pyopenssl/commit/e73818600065821d588af475b024f4eb518c3509"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2019:0085"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-2rcm-phc9-3945"},{"type":"PACKAGE","url":"https://github.com/pyca/pyopenssl"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/pyopenssl/PYSEC-2018-24.yaml"},{"type":"WEB","url":"https://usn.ubuntu.com/3813-1"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00014.html"}],"affected":[{"package":{"name":"pyopenssl","ecosystem":"PyPI","purl":"pkg:pypi/pyopenssl"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17.5.0"}]}],"versions":["0.10","0.11","0.12","0.13","0.13.1","0.14","0.15","0.15.1","0.6","0.7","0.8","0.9","16.0.0","16.1.0","16.2.0","17.0.0","17.1.0","17.2.0","17.3.0","17.4.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2018/10/GHSA-2rcm-phc9-3945/GHSA-2rcm-phc9-3945.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
