DATE | CVE | VULNERABILITY TITLE | RISK |
---|---|---|---|
2014-12-15 | CVE-2014-6053 | Data Processing Errors vulnerability in multiple products 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. | 5.0 |
2014-12-15 | CVE-2014-6052 | Improper Input Validation vulnerability in multiple products 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. | 7.5 |
2014-10-06 | CVE-2014-6054 | Numeric Errors vulnerability in multiple products 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. | 4.3 |
2014-09-30 | CVE-2014-6055 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products 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. | 6.5 |
2014-09-30 | CVE-2014-6051 | Numeric Errors vulnerability in multiple products 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. | 7.5 |
2006-07-18 | CVE-2006-2450 | Unspecified vulnerability in Libvncserver 0.7.1 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. | 7.5 |
