Details
A vulnerability classified as critical has been found in LibTIFF (unknown version). This affects the function TIFFReadRGBAImageOriented. The manipulation with an unknown input leads to a write-what-where condition vulnerability. CWE is classifying the issue as CWE-123. Any condition where the attacker has the ability to write an arbitrary value to an arbitrary location, often as the result of a buffer overflow. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.
