CVE-2015-20109 Information

Description

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.
