CVE-2026-77680

libsoup contains an algorithmic complexity flaw in its HTTP Range header processing that persists after the CVE-2025-32907 fix. The root cause is that the coalescing loop in soup_message_headers_get_ranges_internal() uses g_array_remove_index() for each merged range, resulting in O(N²) work when ...

icalendar has Algorithmic Complexity in Equality

Summary Component.eq compares subcomponents in O2^n time relative to nesting depth. Because the parser accepts arbitrarily nested components, a sub-kilobyte .ics file is enough to make a single equality check run for minutes or hang indefinitely. Any application that compares parsed components ==...
