descriptionThe remote host is affected by the vulnerability described in GLSA-200908-10 (Dillo: User-assisted execution of arbitrary code) Tilei Wang reported an integer overflow in the Png_datainfo_callback() function, possibly leading to a heap-based buffer overflow. Impact : A remote attacker could entice a user to open an HTML document containing a specially crafted, large PNG image, possibly resulting in the execution of arbitrary code with the privileges of the user running the application. Workaround : There is no known workaround at this time.
