A stack-based buffer overflow vulnerability exists in the Dia diagram editor when processing Network Bus objects from Dia XML project files. The vulnerability arises because the number of bus handles is read from the file without validating an upper bound, leading to excessive stack allocation and potential stack overflow when moving a bus handle. This can cause a crash (SIGSEGV) and possible corruption of stack frames or return addresses. The issue affects Dia version 0.98.0 and earlier versions containing the vulnerable code. Exploitation requires opening a crafted .dia file and manipulating bus handles. Join the discussion | GCVE Database | 08/26/2026, 13:19:00 UTC Added: 10/17/2026, 22:23:50 UTC |
