  "description": "This libtiff provides support for the Tag Image File Format (TIFF), a widely used format for storing image data. The latest version of the TIFF specification is available on-line in several different formats.And contains command-line programs for manipulating TIFF format image files using the libtiff library.\r\n\r\nSecurity Fix(es):\r\n\r\nLibTIFF 4.4.0 has an out-of-bounds read in extractImageSection in tools/tiffcrop.c:6905, allowing attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit 48d6ece8.(CVE-2022-2953)\r\n\r\nThere is a double free or corruption in rotateImage() at tiffcrop.c:8839 found in libtiff 4.4.0rc1(CVE-2022-2519)\r\n\r\nIt was found in libtiff 4.4.0rc1 that there is an invalid pointer free operation in TIFFClose() at tif_close.c:131 called by tiffcrop.c:2522 that can cause a program crash and denial of service while processing crafted input.(CVE-2022-2521)",
