Libtiff: libtiff: arbitrary code execution or denial of service via signed integer overflow in tiff file processing

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.

整数溢出或超界折返

LibTIFF 输入验证错误漏洞

LibTIFF是LibTIFF开源的一个读写TIFF（标签图像文件格式）文件的库。该库包含一些处理TIFF文件的命令行工具。 LibTIFF存在输入验证错误漏洞，该漏洞源于putcontig8bitYCbCr44tile函数存在整数溢出，可能导致越界堆写入、拒绝服务或执行任意代码。
