Package : libytnef
CVE ID : CVE-2017-6298 CVE-2017-6299 CVE-2017-6300 CVE-2017-6301
CVE-2017-6302 CVE-2017-6303 CVE-2017-6304 CVE-2017-6305
CVE-2017-6306 CVE-2017-6800 CVE-2017-6801 CVE-2017-6802
Debian Bug :

Several issues were discovered in libytnef, a library used to decode
application/ms-tnef e-mail attachments. Multiple heap overflows,
out-of-bound writes and reads, NULL pointer dereferences and infinite
loops could be exploited by tricking a user into opening a maliciously
crafted winmail.dat file.

For the stable distribution (jessie), these problems have been fixed in
version 1.5-6+deb8u1.

For the upcoming stable (stretch) and unstable (sid) distributions,
these problems have been fixed in version 1.9.2-1.

We recommend that you upgrade your libytnef packages.
