Date Reported:

27 Mar 2008

Affected Packages:

exiftags

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 457062.
In Mitre's CVE dictionary: CVE-2007-6354, CVE-2007-6355, CVE-2007-6356.

More information:

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 oldstable distribution (sarge), these problems have been fixed in version 0.98-1.1+0sarge1.

For the stable distribution (etch), these problems have been fixed in version 0.98-1.1+etch4.

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

Fixed in:

Debian GNU/Linux 3.1 (sarge)
