CVE-2006-5397 medium priority: Ubuntu including 1 source packages (libx11), 4 status rows across 4 suites (dapper, edgy, feisty, upstream): not-affected 3, needs-triage 1.
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.
