  - A vulnerability was determined in Freedesktop Poppler 26.06.0/26.07.0/26.08.0. This impacts the function
    FoFiTrueType::cvtSfnts of the file fofi/FoFiTrueType.cc. This manipulation causes integer overflow. The
    attack can only be executed locally. The exploit has been publicly disclosed and may be utilized. Patch
