{"id":"BIT-libpython-2020-14422","details":"Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12; v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2.","aliases":["BIT-python-2020-14422","BIT-python-min-2020-14422","CVE-2020-14422","PSF-2020-3"],"modified":"2025-08-11T15:13:44.340151Z","published":"2025-08-11T13:51:28.699Z","database_specific":{"cpes":["cpe:2.3:a:python:python:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00003.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00006.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00032.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00041.html"},{"type":"WEB","url":"https://bugs.python.org/issue41004"},{"type":"WEB","url":"https://github.com/python/cpython/pull/20956"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2020/07/msg00011.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/05/msg00016.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/36XI3EEQNMHGOZEI63Y7UV6XZRELYEAU/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CNHPQGSP2YM3JAUD2VAMPXTIUQTZ2M2U/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CTUNTBJ3POHONQOTLEZC46POCIYYTAKZ/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FCCZTAYZATTNSNEAXWA7U3HCO2OVQKT5/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LE4O3PNDNNOMSKHNUKZKD3NGHIFUFDPX/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NTBKKOLFFNHG6CM4ACDX4APHSD5ZX5N4/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OXI72HIHMXCQFWTULUXDG7VDA2BCYL4Y/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/V3TALOUBYU2MQD4BPLRTDQUMBKGCAXUA/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/V53P2YOLEQH4J7S5QHXMKMZYFTVVMTMO/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VT4AF72TJ2XNIKCR4WEBR7URBJJ4YZRD/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/X36Y523UAZY5QFXZAAORNFY63HLBWX7N/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YILCHHTNLH4GG4GSQBX2MZRKZBXOLCKE/"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-14422"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202008-01"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20200724-0004/"},{"type":"WEB","url":"https://usn.ubuntu.com/4428-1/"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpujan2021.html"}],"affected":[{"package":{"name":"libpython","ecosystem":"Bitnami","purl":"pkg:bitnami/libpython"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.0.0"},{"fixed":"3.5.10"},{"introduced":"3.6.0"},{"fixed":"3.6.12"},{"introduced":"3.7.0"},{"fixed":"3.7.9"},{"introduced":"3.8.0"},{"fixed":"3.8.4"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/libpython/BIT-libpython-2020-14422.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.7.3"}
