CVE-2006-5397: X.org LIBX11

Low severity, CVSS 2.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• X.org LIBX11: version 1.0.2 only; version 1.0.3 only
