TITLE

X.Org Input Device Format String Vulnerability

Trust: 0.9

sources: CNVD: CNVD-2012-7656 // BID: 53150

DESCRIPTION

Format string vulnerability in the LogVHdrMessageVerb function in os/log.c in X.Org X11 1.11 allows attackers to cause a denial of service or possibly execute arbitrary code via format string specifiers in an input device name. X.Org is an open source implementation of the X.Org Foundation for the X Window System. X.Org is prone to a local format-string vulnerability. An attacker may exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201207-04 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: X.Org X Server: Privilege escalation Date: July 09, 2012 Bugs: #412609 ID: 201207-04 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== A format string vulnerability in X.Org X Server may allow local privilege escalation or Denial of Service. NOTE: Exposure to this vulnerability is reduced in Gentoo due to X.Org X Server being built with "-D_FORTIFY_SOURCE=2" by default. Impact ====== A local attacker could gain escalated privileges or cause a Denial of Service condition. Workaround ========== There is no known workaround at this time. Resolution ========== All X.Org X Server 1.11.x users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=x11-base/xorg-server-1.11.4-r1"= All X.Org X Server 1.10.x users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=x11-base/xorg-server-1.10.6-r1"= X.Org X Server 1.9.x is not affected.
