Red Hat Bugzilla – Bug 1259322
CVE-2015-5218 colcrt: global-buffer-overflow
Last modified: 2016-01-22 10:04:52 EST
A flaw was reported in colcrt:
When running colcrt with a big input it crashes because of a global-buffer-overflow caused by a global variable 'page' defined in 'text-utils/colcrt.c:73:9
It is unclear whether this can be used to execute code on the system.
This was fixed in util-linux version 2.27.
Our quick analysis did not confirm a code execution vector, thus this flaw is limited to a local denial of service when running colcrt on a crafted file.
