Package        : exiftags
Vulnerability  : insufficient input sanitizing
Problem type   : local (remote)
Debian-specific: no
CVE Id(s)      : CVE-2007-6354 CVE-2007-6355 CVE-2007-6356
Debian Bug     : 457062

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).

For the stable distribution (etch), these problems have been fixed in
version 0.98-1.1+etch1.

The old stable distribution (sarge) cannot be fixed synchronously
with the Etch version due to a technical limitation in the Debian
archive management scripts.

For the unstable distribution (sid), these problems have been fixed in
version 1.01-0.1.

We recommend that you upgrade your exiftags package.
