Christian Schmid and Meder Kydyraliev (Google Security) discovered a number of vulnerabilities in exiftags, a utility for extracting EXIF metadata from JPEG images. This update merely adds the packages for Debian 3.1 sarge (oldstable) which were missing in the previous DSA. 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). For the stable distribution (etch), these problems have been fixed in version 0.98-1.1+etch1. For the oldstable distribution (sarge), these problems have been fixed in version 0.98-1.1+0sarge1. For the unstable distribution (sid), these problems have been fixed in version 1.01-0.1.
