LibreOffice < 5.1.4 RTF Character Style Index RCE

high Nessus Plugin ID 91974

Language:

Synopsis

An application installed on the remote host is affected by a remote code execution vulnerability.

Description

The version of LibreOffice installed on the remote Windows host is prior to 5.1.4. It is, therefore, affected by a use-after-free error during Rich Text Format (RTF) file parsing due to improper validation of the RTF character style index. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted RTF file, to execute arbitrary code.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to LibreOffice version 5.1.4 or later.
