{"id":"CVE-2024-0450","details":"An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior.\n\nThe zipfile module is vulnerable to “quoted-overlap” zip-bombs which exploit the zip format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile module reject zip archives which overlap entries in the archive.\n\n","aliases":["BIT-libpython-2024-0450","BIT-python-2024-0450","BIT-python-min-2024-0450","PSF-2024-2"],"modified":"2026-04-16T04:37:09.975137989Z","published":"2024-03-19T16:15:09.180Z","related":["ALSA-2024:3347","ALSA-2024:3466","ALSA-2024:4058","ALSA-2024:4078","ALSA-2024:4243","ALSA-2024:9190","ALSA-2024:9192","CGA-93c7-pmh4-f4m2","RLSA-2024:3466","SUSE-SU-2024:1009-1","SUSE-SU-2024:1162-1","SUSE-SU-2024:1556-1","SUSE-SU-2024:1774-1","SUSE-SU-2024:1843-1","SUSE-SU-2024:1844-1","SUSE-SU-2024:1847-1","SUSE-SU-2024:1862-1","SUSE-SU-2024:2479-1","SUSE-SU-2025:20025-1","SUSE-SU-2025:20154-1","SUSE-SU-2025:20374-1","openSUSE-SU-2024:13790-1","openSUSE-SU-2024:13794-1","openSUSE-SU-2024:13799-1","openSUSE-SU-2024:13800-1","openSUSE-SU-2024:13983-1"],"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/03/20/5"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/03/msg00024.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/T3IGRX54M7RNCQOXVQO5KQKTGWCOABIM/"},{"type":"WEB","url":"https://www.bamsoftware.com/hacks/zipbomb/"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/03/msg00025.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/U5VHWS52HGD743C47UMCSAK2A773M2YE/"},{"type":"WEB","url":"https://mail.python.org/archives/list/security-announce@python.org/thread/XELNUX2L3IOHBTFU7RQHCY6OUVEWZ2FG/"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/11/msg00005.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/12/msg00000.html"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20250411-0005/"},{"type":"REPORT","url":"https://github.com/python/cpython/issues/109858"},{"type":"FIX","url":"https://github.com/python/cpython/commit/30fe5d853b56138dbec62432d370a1f99409fc85"},{"type":"FIX","url":"https://github.com/python/cpython/commit/66363b9a7b9fe7c99eba3a185b74c5fdbf842eba"},{"type":"FIX","url":"https://github.com/python/cpython/commit/70497218351ba44bffc8b571201ecb5652d84675"},{"type":"FIX","url":"https://github.com/python/cpython/commit/a956e510f6336d5ae111ba429a61c3ade30a7549"},{"type":"FIX","url":"https://github.com/python/cpython/commit/d05bac0b74153beb541b88b4fca33bf053990183"},{"type":"FIX","url":"https://github.com/python/cpython/commit/fa181fcf2156f703347b03a3b1966ce47be8ab3b"},{"type":"FIX","url":"https://github.com/python/cpython/commit/a2c59992e9e8d35baba9695eb186ad6c6ff85c51"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"30fe5d853b56138dbec62432d370a1f99409fc85"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"66363b9a7b9fe7c99eba3a185b74c5fdbf842eba"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"70497218351ba44bffc8b571201ecb5652d84675"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"a2c59992e9e8d35baba9695eb186ad6c6ff85c51"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"a956e510f6336d5ae111ba429a61c3ade30a7549"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"d05bac0b74153beb541b88b4fca33bf053990183"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"fa181fcf2156f703347b03a3b1966ce47be8ab3b"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"30fe5d853b56138dbec62432d370a1f99409fc85"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"66363b9a7b9fe7c99eba3a185b74c5fdbf842eba"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"70497218351ba44bffc8b571201ecb5652d84675"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"a2c59992e9e8d35baba9695eb186ad6c6ff85c51"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"a956e510f6336d5ae111ba429a61c3ade30a7549"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"d05bac0b74153beb541b88b4fca33bf053990183"}]},{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"fa181fcf2156f703347b03a3b1966ce47be8ab3b"}]}],"versions":["v0.9.8","v0.9.9","v1.0.1","v1.0.2","v1.1","v1.1.1","v1.2","v1.2b1","v1.2b2","v1.2b3","v1.2b4","v1.3","v1.3b1","v1.4","v1.4b1","v1.4b2","v1.4b3","v1.5","v1.5.1","v1.5.2","v1.5.2a1","v1.5.2a2","v1.5.2b1","v1.5.2b2","v1.5.2c1","v1.5a1","v1.5a2","v1.5a3","v1.5a4","v1.5b1","v1.5b2","v1.6a1","v1.6a2","v2.0","v2.0b1","v2.0b2","v2.0c1","v2.1","v2.1a1","v2.1a2","v2.1b1","v2.1b2
