Description Thomas Leroy 2023-06-26 08:42:38 UTC 
CVE-2015-20109

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.
