Описание
A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations, potentially causing a denial of service (application crash) or arbitrary code execution.
Отчет
A flaw in the libtiff library, affecting the processing of specially crafted TIFF files, could lead to a denial of service or potentially arbitrary code execution. This vulnerability, caused by a signed integer overflow during TIFF image processing, results in an out-of-bounds heap write. Red Hat products that process untrusted TIFF files using libtiff may be impacted.
Меры по смягчению последствий
To mitigate this issue, avoid processing untrusted or maliciously crafted TIFF files with applications linked against the libtiff library. If processing untrusted TIFF files is unavoidable, consider running the affected applications within a sandboxed environment to limit the potential impact of successful exploitation. This operational control helps contain the effects of an out-of-bounds write, reducing the risk of denial of service or arbitrary code execution.
