Bug 695536 (CVE-2019-9854) – <app-office/libreoffice{,-bin}-{6.2.7.1,6.3.1.2}: Unsafe URL assembly flaw in allowed script location check (CVE-2019-9854)

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description GLSAMaker/CVETool Bot 2019-09-24 12:17:49 UTC]

CVE-2019-9854 (https://nvd.nist.gov/vuln/detail/CVE-2019-9854):
  LibreOffice has a feature where documents can specify that pre-installed
  macros can be executed on various script events such as mouse-over,
  document-open etc. Access is intended to be restricted to scripts under the
  share/Scripts/python, user/Scripts/python sub-directories of the LibreOffice
  install. Protection was added, to address CVE-2019-9852, to avoid a
  directory traversal attack where scripts in arbitrary locations on the file
  system could be executed by employing a URL encoding attack to defeat the
  path verification step. However this protection could be bypassed by taking
  advantage of a flaw in how LibreOffice assembled the final script URL
  location directly from components of the passed in path as opposed to solely
  from the sanitized output of the path verification step. This issue affects:
  Document Foundation LibreOffice 6.2 versions prior to 6.2.7; 6.3 versions
  prior to 6.3.1.
