{"id":"CVE-2020-1752","details":"A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32.","modified":"2026-04-16T04:36:18.933264623Z","published":"2020-04-30T17:15:13.067Z","related":["SUSE-SU-2020:0820-1","SUSE-SU-2020:0832-1","SUSE-SU-2022:1123-1","openSUSE-SU-2020:0467-1","openSUSE-SU-2024:10792-1"],"references":[{"type":"WEB","url":"https://sourceware.org/git/gitweb.cgi?p=glibc.git%3Bh=ddc650e9b3dc916eab417ce9f79e67337b05035c"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4416-1/"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202101-20"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20200511-0005/"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1752"},{"type":"FIX","url":"https://sourceware.org/bugzilla/show_bug.cgi?id=25414"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-1752.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"2.32.0"}]},{"events":[{"introduced":"0"},{"last_affected":"16.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.04"}]},{"events":[{"introduced":"0"},{"last_affected":"19.10"}]},{"events":[{"introduced":"9.5"}]},{"events":[{"introduced":"0"},{"last_affected":"10.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
