| Doc Text: |
A flaw was found in libpng. A local attacker could exploit this vulnerability by manipulating the width/height arguments in the `do_pnm2png` function of the `pnm2png` component. This manipulation causes a heap-based buffer overflow, which could lead to information disclosure and denial of service (DoS).
