Attack-Flow Graph

Executive Summary

This vulnerability is a local code execution flaw in CrossWire Xiphos versions 4.3.2 and earlier. It exists in the src/main/url.cc and src/gtk/menu_popup.c components, allowing a local attacker to run arbitrary code on the affected system.

Detection Guidance

To detect CVE-2026-79079, check if Xiphos version 4.3.2 or earlier is installed using package managers like 'dpkg -l xiphos' or 'rpm -qa xiphos'. Verify if the vulnerable src/main/url.cc and src/gtk/menu_popup.c files exist in the Xiphos installation directory. Monitor for unexpected file creation in /tmp, such as '/tmp/xiphos_cve_2026_79079_proof', which may indicate exploitation.
