CVE-2015-4469 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:16.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libmspack package and not the libmspack package as distributed by Ubuntu.
The chmd_read_headers function in chmd.c in libmspack before 0.5 does not validate name lengths, which allows remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted CHM file.
