Описание
A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscanner_gettoken() function writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one error in the loop boundary check. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution.
Отчет
This Moderate flaw in GIMP's PNM file parser could lead to memory corruption and potentially arbitrary code execution or denial of service. The vulnerability requires a user to open a specially crafted PNM image file with GIMP. As a desktop application, the impact is limited to the user's session and requires user interaction.
Меры по смягчению последствий
None — requires opening a crafted PNM file.
