The Xinput module (modules/im/ximcp/imLcIm.c) in X.Org libX11 1.0.2 and 1.0.3 opens a file for reading twice using the same file descriptor, which causes a file descriptor leak that allows local users to read files specified by the XCOMPOSEFILE environment variable via the duplicate file descriptor.

Security readout for executives and security teams

This is an old local information disclosure issue in X.Org libX11. A file handling bug in the Xinput module can leak a duplicate file descriptor, letting a local user read a file referenced through XCOMPOSEFILE. Sources do not show remote exploitation or confirmed active exploitation. Exposure is most likely limited to legacy Unix or Linux systems still running X.Org libX11 1.0.2 or 1.0.3 with local interactive users. Modern supported distributions are unlikely to carry these exact versions, but old appliances, thin clients, or unmaintained desktops should be checked. Treat this as a low-priority legacy hygiene issue unless affected systems support multiple local users or privileged desktop applications. Prioritize normal patching, asset cleanup, and unsupported system retirement over emergency response. Mitigation focus: Inventory hosts for X.Org libX11 1.0.2 or 1.0.3.; Apply vendor-supported libX11 updates or distribution security packages.; Retire or isolate unsupported systems that cannot receive X11 updates..
