Improper Input Validation vulnerability in GStreamer integration of The Document Foundation LibreOffice allows an attacker to execute arbitrary GStreamer plugins. In affected versions the filename of the embedded video is not sufficiently escaped when passed to GStreamer enabling an attacker to run arbitrary gstreamer plugins depending on what plugins are installed on the target system.

Detection & IOCsextracted from sources · hover to see the quote

  • The attack vector involves an embedded video within a document file where the filename is not sufficiently escaped before being passed to GStreamer. Detection should focus on LibreOffice processes spawning unexpected GStreamer plugin child processes.
  • Suspicious LibreOffice documents containing embedded video content should be treated as potentially malicious delivery vehicles for this exploit. Monitor for LibreOffice opening files that trigger GStreamer plugin execution.
  • ·Exploitability depends on which GStreamer plugins are installed on the target system; impact varies per host configuration.
  • ·The vulnerability is scoped as local exploitation per Debian's security tracker classification.
  • ·Red Hat will not fix this in RHEL 8 and RHEL 9 libreoffice:flatpak packages; RHEL 6 is out of support scope.
