CVE-2015-8984: GNU Glibc

Medium severity, CVSS 5.9. EPSS: 2.4% chance of exploitation in the next 30 days.

The fnmatch function 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) via a malformed pattern, which triggers an out-of-bounds read.

Affected products

• GNU Glibc: up to and including 2.21
