An issue was discovered in certain Apple products. iOS before 11 is affected. macOS before 10.13 is affected. tvOS before 11 is affected. watchOS before 4 is affected. The issue involves the "Kernel" component. It allows attackers to obtain sensitive network-activity information about arbitrary apps via a crafted app.
LibTIFF 4.0.3 allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact via a crafted TIFF image, as demonstrated by failure of tif_next.c to verify that the BitsPerSample value is 2, and the t2p_sample_lab_signed_to_unsigned function in tiff2pdf.c.
The _TIFFmalloc function in tif_unix.c in LibTIFF 4.0.3 does not reject a zero size, which allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image that is mishandled by the TIFFWriteScanline function in tif_write.c, as demonstrated by tiffdither.
An issue was discovered in certain Apple products. iOS before 11.2 is affected. macOS before 10.13.2 is affected. tvOS before 11.2 is affected. The issue involves the "Kernel" component. It allows local users to bypass intended memory-read restrictions or cause a denial of service (system crash).
An issue was discovered in certain Apple products. macOS before 10.13.2 is affected. The issue involves the "Intel Graphics Driver" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.
An issue was discovered in certain Apple products. macOS before 10.13.2 is affected. The issue involves the "Screen Sharing Server" component. It allows attackers to obtain root privileges for reading files by leveraging screen-sharing access.
An issue was discovered in certain Apple products. macOS before 10.13.2 is affected. The issue involves the "IOAcceleratorFamily" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.
An issue was discovered in certain Apple products. iOS before 11.2 is affected. macOS before 10.13.2 is affected. tvOS before 11.2 is affected. watchOS before 4.2 is affected. The issue involves the "IOKit" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.
