In KDE Krita before 5.2.13, loading a manipulated TGA file could result in a heap-based buffer overflow in plugins/impex/tga/kis_tga_import.cpp (aka KisTgaImport). Control flow proceeds even when a number of pixels becomes negative.

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dla-4395 advisory.
