SUSE 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...

SUSE CVE-2010-5304

A NULL pointer dereference flaw was found in the way LibVNCServer before 0.9.9 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...

SUSE 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...

SUSE 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...

SUSE 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...

SUSE 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...

SUSE CVE-2016-9941

Heap-based buffer overflow in rfbproto.c in LibVNCClient in LibVNCServer before 0.9.11 allows remote servers to cause a denial of service application crash or possibly execute arbitrary code via a crafted FramebufferUpdate message containing a subrectangle outside of the client drawing area...

SUSE CVE-2017-18922

It was discovered that websockets.c in LibVNCServer prior to 0.9.12 did not properly decode certain WebSocket frames. A malicious attacker could exploit this by sending specially crafted WebSocket frames to a server, causing a heap-based buffer overflow...

SUSE CVE-2018-7225

An issue was discovered in LibVNCServer through 0.9.11. rfbProcessClientNormalMessage in rfbserver.c does not sanitize msg.cct.length, leading to access to uninitialized and potentially sensitive data or possibly unspecified other impact e.g., an integer overflow via specially crafted VNC packets...

SUSE CVE-2018-20750

LibVNC through 0.9.12 contains a heap out-of-bounds write vulnerability in libvncserver/rfbserver.c. The fix for CVE-2018-15127 was incomplete...

SUSE CVE-2018-21247
