{"id":"CVE-2015-20109","details":"end_pattern (called from internal_fnmatch) in the GNU C Library (aka glibc or libc6) before 2.22 might allow context-dependent attackers to cause a denial of service (application crash), as demonstrated by use of the fnmatch library function with the **(!() pattern. NOTE: this is not the same as CVE-2015-8984; also, some Linux distributions have fixed CVE-2015-8984 but have not fixed this additional fnmatch issue.","modified":"2025-08-09T19:01:26Z","published":"2023-06-25T17:15:14Z","references":[{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20230731-0009/"},{"type":"REPORT","url":"https://sourceware.org/bugzilla/show_bug.cgi?id=18036"}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
