Description

Christian Schmid and Meder Kydyraliev (Google Security) discovered a number of vulnerabilities in exiftags, a utility for extracting EXIF metadata from JPEG images. The Common Vulnerabilities and Exposures project identified the following three problems :

  • CVE-2007-6354 Inadequate EXIF property validation could lead to invalid memory accesses if executed on a maliciously crafted image, potentially including heap corruption and the execution of arbitrary code.

  • CVE-2007-6355 Flawed data validation could lead to integer overflows, causing other invalid memory accesses, also with the potential for memory corruption or arbitrary code execution.

  • CVE-2007-6356 Cyclical EXIF image file directory (IFD) references could cause a denial of service (infinite loop).
