2014-09-30 CVE-2014-6055 Multiple stack-based buffer overflows in the File Transfer feature in rfbserver.c in LibVNCServer 0.9.9 and earlier allow remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via a (1) long file or (2) directory name or the (3) FileTime attribute in a rfbFileTransferOffer message. Debian_linux, Fedora, Libvncserver, Enterprise_linux_server_aus, Enterprise_linux_server_eus N/A
2014-12-15 CVE-2014-6052 The HandleRFBServerMessage function in libvncclient/rfbproto.c in LibVNCServer 0.9.9 and earlier does not check certain malloc return values, which allows remote VNC servers to cause a denial of service (application crash) or possibly execute arbitrary code by specifying a large screen size in a (1) FramebufferUpdate, (2) ResizeFrameBuffer, or (3) PalmVNCReSizeFrameBuffer message. Ubuntu_linux, Debian_linux, Libvncserver, Solaris N/A
2014-10-06 CVE-2014-6054 The rfbProcessClientNormalMessage function in libvncserver/rfbserver.c in LibVNCServer 0.9.9 and earlier allows remote attackers to cause a denial of service (divide-by-zero error and server crash) via a zero value in the scaling factor in a (1) PalmVNCSetScaleFactor or (2) SetScale message. Ubuntu_linux, Debian_linux, Libvncserver N/A
2014-09-30 CVE-2014-6051 Integer overflow in the MallocFrameBuffer function in vncviewer.c in LibVNCServer 0.9.9 and earlier allows remote VNC servers to cause a denial of service (crash) and possibly execute arbitrary code via an advertisement for a large screen size, which triggers a heap-based buffer overflow. Debian_linux, Fedora, Libvncserver, Solaris, Enterprise_linux_server_aus, Enterprise_linux_server_eus N/A
2014-12-15 CVE-2014-6053 The rfbProcessClientNormalMessage function in libvncserver/rfbserver.c in LibVNCServer 0.9.9 and earlier does not properly handle attempts to send a large amount of ClientCutText data, which allows remote attackers to cause a denial of service (memory consumption or daemon crash) via a crafted message that is processed by using a single unchecked malloc. Ubuntu_linux, Debian_linux, Libvncserver N/A
2006-07-18 CVE-2006-2450 auth.c in LibVNCServer 0.7.1 allows remote attackers to bypass authentication via a request in which the client specifies an insecure security type such as "Type 1 - None", which is accepted even if it is not offered by the server, a different issue than CVE-2006-2369. Libvncserver N/A
