CVE-2018-10119 — Libreoffice Libreoffice security vulnerability

High CVSS 7.8

sot/source/sdstor/stgstrms.cxx in LibreOffice before 5.4.5.1 and 6.x before 6.0.1.1 uses an incorrect integer data type in the StgSmallStrm class, which allows remote attackers to cause a denial of service (use-after-free with write access) or possibly have unspecified other impact via a crafted document that uses the structured storage ole2 wrapper file format.

Matched remediation archetype

Use-after-free, double free, and expired resource use

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace ownership, references, callbacks, asynchronous tasks, and teardown paths around the affected object or resource.
  • Identify reachable inputs and timing or state transitions that can release the object while references remain.
  • Confirm affected builds, allocators, feature flags, architectures, and process privileges.

Remediate safely

  • Apply the maintained ownership or lifetime fix and rebuild all artifacts containing the affected native code.
  • Use explicit ownership, safe reference management, cancellation and join semantics, and idempotent teardown.
  • Add deterministic lifetime tests plus isolated sanitizer and concurrency coverage for shutdown and error paths.
