A flaw was identified in libsoup, a widely used HTTP library in GNOME-based systems. When processing specially crafted HTTP Range headers, the library may improperly validate requested byte ranges.

Exploitation requires a vulnerable configuration and access to a server using the embedded SoupServer component.
