CVE-2026-32854

Name of the Vulnerable Software and Affected Versions LibVNCServer versions prior to the commit dc78dee LibVNCServer version 0.9.15

Description The software contains null pointer dereference issues in the HTTP proxy handlers within the httpProcessInput() function in httpd.c. These issues allow remote attackers to cause a denial of service by sending specially crafted HTTP requests. Specifically, missing validation of the strchr() return values in the CONNECT and GET proxy handling paths can trigger null pointer dereferences, leading to a server crash when httpd and proxy features are enabled.

Recommendations Update LibVNCServer to a version after the commit dc78dee.
