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.
AnalysisAI
LibVNCServer versions 0.9.15 and earlier contain null pointer dereference vulnerabilities in the HTTP proxy handlers within httpd.c that allow remote attackers to cause denial of service by sending specially crafted HTTP requests. The vulnerability affects systems with both httpd and proxy features enabled, and while no CVSS score or EPSS data is currently available, the presence of a public patch and vendor advisory indicates this is a recognized security issue requiring prompt attention.
