An issue was discovered in ytnef before 1.9.1. This is related to a patch described as "9 of 9. Directory Traversal using the filename; SanitizeFilename function in settings.c."

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4615-1 advisory.

    It was discovered that Yerase's TNEF had null pointer dereferences, infinite loop, buffer overflow, out of     bounds reads, directory traversal issues and other vulnerabilities. An attacker could use those issues to     cause a crash and consequently a denial of service. (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)

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.
