Title:	CentOS Update for libvncserver CESA-2014:1826 centos6
Summary:	Check the version of libvncserver
Description:	Summary: Check the version of libvncserver Vulnerability Insight: LibVNCServer is a library that allows for easy creation of VNC server or client functionality. An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way screen sizes were handled by LibVNCServer. A malicious VNC server could use this flaw to cause a client to crash or, potentially, execute arbitrary code in the client. (CVE-2014-6051) A NULL pointer dereference flaw was found in LibVNCServer's framebuffer setup. A malicious VNC server could use this flaw to cause a VNC client to crash. (CVE-2014-6052) A NULL pointer dereference flaw was found in the way LibVNCServer handled certain ClientCutText message. A remote attacker could use this flaw to crash the VNC server by sending a specially crafted ClientCutText message from a VNC client. (CVE-2014-6053) A divide-by-zero flaw was found in the way LibVNCServer handled the scaling factor when it was set to '0'. A remote attacker could use this flaw to crash the VNC server using a malicious VNC client. (CVE-2014-6054) Two stack-based buffer overflow flaws were found in the way LibVNCServer handled file transfers. A remote attacker could use this flaw to crash the VNC server using a malicious VNC client. (CVE-2014-6055) Red Hat would like to thank oCERT for reporting these issues. oCERT acknowledges Nicolas Ruff as the original reporter.
