Description

Meder Kydyraliev discovered that exiv2 did not correctly handle certain EXIF headers. If a user or automated system were tricked into processing a specially crafted image, a remote attacker could cause the application linked against libexiv2 to crash, leading to a denial of service, or possibly executing arbitrary code with user privileges. (CVE-2007-6353)

Joakim Bildrulle discovered that exiv2 did not correctly handle Nikon lens EXIF information. If a user or automated system were tricked into processing a specially crafted image, a remote attacker could cause the application linked against libexiv2 to crash, leading to a denial of service. (CVE-2008-2696).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
