| CVE-2026-32853 | 1 Libvncserver | 1 Libvncserver | 2026-03-25 | 5.4 Medium |
| LibVNCServer versions 0.9.15 and prior (fixed in commit 009008e) contain a heap out-of-bounds read vulnerability in the UltraZip encoding handler that allows a malicious VNC server to cause information disclosure or application crash. Attackers can exploit improper bounds checking in the HandleUltraZipBPP() function by manipulating subrectangle header counts to read beyond the allocated heap buffer. | ||||
| CVE-2026-32854 | 1 Libvncserver | 1 Libvncserver | 2026-03-25 | 5.3 Medium |
| LibVNCServer versions 0.9.15 and prior (fixed in commit dc78dee) contain null pointer dereference vulnerabilities in the HTTP proxy handlers within httpProcessInput() in httpd.c that allow remote attackers to cause a denial of service by sending specially crafted HTTP requests. Attackers can exploit missing validation of strchr() return values in the CONNECT and GET proxy handling paths to trigger null pointer dereferences and crash the server when httpd and proxy features are enabled. | ||||
| CVE-2014-6052 | 5 Canonical, Debian, Libvncserver and 2 more | 5 Ubuntu Linux, Debian Linux, Libvncserver and 2 more | 2025-04-12 | N/A |
| 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. | ||||
| CVE-2014-6053 | 4 Canonical, Debian, Libvncserver and 1 more | 4 Ubuntu Linux, Debian Linux, Libvncserver and 1 more | 2025-04-12 | N/A |
| 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. | ||||
| CVE-2014-6055 | 4 Debian, Fedoraproject, Libvncserver and 1 more | 7 Debian Linux, Fedora, Libvncserver and 4 more | 2025-04-12 | N/A |
| 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. | ||||
| CVE-2014-6054 | 4 Canonical, Debian, Libvncserver and 1 more | 4 Ubuntu Linux, Debian Linux, Libvncserver and 1 more | 2025-04-12 | N/A |
| 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. | ||||
| CVE-2014-6051 | 5 Debian, Fedoraproject, Libvncserver and 2 more | 8 Debian Linux, Fedora, Libvncserver and 5 more | 2025-04-12 | N/A |
| 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. | ||||
| CVE-2006-2450 | 1 Libvncserver | 1 Libvncserver | 2025-04-03 | N/A |
| 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. | ||||
