LibreOffice is typically bundled with LibreLogo, a programmable turtle vector graphics script, which can execute arbitrary python commands contained with the document it is launched from. LibreOffice also has a feature where documents can specify that pre-installed scripts can be executed on various document script events such as mouse-over, etc. Protection was added to block calling LibreLogo from script event handers. However a Windows 8.3 path equivalence handling flaw left LibreOffice vulnerable under Windows that a document could trigger executing LibreLogo via a Windows filename pseudonym. This issue affects: Document Foundation LibreOffice 6.2 versions prior to 6.2.7; 6.3 versions prior to 6.3.1.

This update for libreoffice fixes the following issues: &#9; Updated to version 6.2.7.1.

Security issues fixed :

  - CVE-2019-9854: Fixed unsafe URL assembly flaw     (bsc#1149944).

  - CVE-2019-9855: Fixed path equivalence handling flaw     (bsc#1149943)

This update was imported from the SUSE:SLE-15:Update update project.

The version of LibreOffice installed on the remote Windows host is prior to 6.2.7 or 6.3.x prior to 6.3.1. It is, therefore, affected by the following vulnerabilities:

  - A directory traversal vulnerability resulting from a feature in LibreOffice which allows documents to     specify pre-installed macros that can be executed on various script events. Only scripts under the     'share/Scripts/python' and /user/Scripts/python' sub-directories of the LibreOffice install should be     accessible. Previous protection to address CVE-2019-9852 to avoid a similar attack was added, however this     protection can be bypassed due to a flaw in how LibreOffice assembles the final script URL location. This     flaw can be exploited to allow scripts in arbitrary locations on the file system to be executed.     (CVE-2019-9854)

  - An arbitrary script execution vulnerability caused by a flaw allowing event-based execution of Python     scripts within a document. Previous protection was added to address this flaw, however due to a Windows     8.3 path equivalence flaw, Windows systems are still vulnerable via Windows filename pseudonyms. Note,     LibreLogo must be installed for this vulnerability to be exploitable, however LibreLogo is frequently     bundled with LibreOffice. (CVE-2019-9855)

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