    descriptionIt was discovered that LibRaw incorrectly handled photo files. If a user or automated system were tricked into processing a specially crafted photo file, a remote attacker could cause applications linked against LibRaw to crash, resulting in a denial of service, or possibly execute arbitrary code. 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.
