Package : tnef
CVE ID : CVE-2017-6307 CVE-2017-6308 CVE-2017-6309 CVE-2017-6310
Debian Bug : 856117
Eric Sesterhenn, from X41 D-Sec GmbH, discovered several
vulnerabilities in tnef, a tool used to unpack MIME attachments of
type "application/ms-tnef". Multiple heap overflows, type confusions
and out of bound reads and writes could be exploited by tricking a
user into opening a malicious attachment. This would result in denial
of service via application crash, or potential arbitrary code
execution.
For the stable distribution (jessie), these problems have been fixed in
version 1.4.9-1+deb8u1.
We recommend that you upgrade your tnef packages.
