CWE-772  (opens in a new tab)

How to fix?

Upgrade Echo:latest glibc to version 2.25-3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

The glob function in glob.c in the GNU C Library (aka glibc or libc6) before 2.27, when invoked with GLOB_TILDE, could skip freeing allocated memory when processing the ~ operator with a long user name, potentially leading to a denial of service (memory leak).
