CVE-2017-9146 (opens in a new tab)How to fix?
Upgrade Debian:12 libytnef to version 1.9.3-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libytnef package and not the libytnef package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
The TNEFFillMapi function in lib/ytnef.c in libytnef in ytnef through 1.9.2 does not ensure a nonzero count value before a certain memory allocation, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted tnef file.
