The (1) XvQueryAdaptors and (2) XvQueryEncodings functions in X.org libXv before 1.0.11 allow remote X servers to trigger out-of-bounds memory access operations via vectors involving length specifications in received data.

Security readout for executives and security teams

CVE-2016-5407 is a memory-safety flaw in X.org libXv before 1.0.11. A malicious or compromised remote X server could send malformed length values that cause client applications using libXv to read or access memory out of bounds. Exposure is most likely on Linux or Unix systems with X.org libXv older than 1.0.11, especially where users run X clients against remote X servers. The bundle does not identify broader affected product versions beyond libXv. Treat as a focused workstation and Unix graphics-stack patching issue. It is not KEV-listed in the bundle, but remote-server-triggered memory access makes timely remediation appropriate where X11 workflows cross trust boundaries. Mitigation focus: Update libXv to version 1.0.11 or a distro-fixed package.; Apply relevant vendor advisories from Gentoo, Fedora, or your platform vendor.; Avoid connecting X clients to untrusted remote X servers until patched..
