tnef

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 944851.
In Mitre's CVE dictionary: CVE-2019-18849.

More information:

In tnef, an attacker may be able to write to the victim's .ssh/authorized_keys file via an e-mail message with a crafted winmail.dat application/ms-tnef attachment, because of a heap-based buffer over-read involving strdup.

For Debian 8 Jessie, this problem has been fixed in version 1.4.9-1+deb8u4.

We recommend that you upgrade your tnef packages.
