CVE-2015-4467 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:17.04.
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_init_decomp function in chmd.c in libmspack before 0.5 does not properly validate the reset interval, which allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted CHM file.
