Exploitation vector: Local access
Exploit availability: No public exploit available
Vulnerable software:
LibreOffice
Software vendor:
LibreOffice

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to an error when processing encrypted files in LibreOffice. If LibreOffice has an encrypted document open and crashes, that document is auto-saved encrypted. On restart, LibreOffice offers to restore the document and prompts for the password to decrypt it. If the recovery is successful, and if the file format of the recovered document was not LibreOffice's default ODF file format, then affected versions of LibreOffice default that subsequent saves of the document are unencrypted.

This may lead to a user accidentally saving a MSOffice file format document unencrypted while believing it to be encrypted.


Remediation
