Title:	Mageia: Security Advisory (MGASA-2015-0073)
Summary:	The remote host is missing an update for the 'x11-server' package(s) announced via the MGASA-2015-0073 advisory.
Description:	Summary: The remote host is missing an update for the 'x11-server' package(s) announced via the MGASA-2015-0073 advisory. Vulnerability Insight: Updated x11-server packages fix security vulnerability: Olivier Fourdan from Red Hat has discovered a protocol handling issue in the way the X server code base handles the XkbSetGeometry request, where the server trusts the client to send valid string lengths. A malicious client with string lengths exceeding the request length can cause the server to copy adjacent memory data into the XKB structs. This data is then available to the client via the XkbGetGeometry request. This can lead to information disclosure issues, as well as possibly a denial of service if a similar request can cause the server to crash (CVE-2015-0255). Affected Software/OS: 'x11-server' package(s) on Mageia 4. Solution: Please install the updated package(s). CVSS Score: 6.4 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:P
