libjpeg-turbo vulnerabilities

The fill_input_buffer function in jdatasrc.c in libjpeg-turbo 1.5.1 allows remote attackers to cause a denial of service (invalid memory access and application crash) or possibly have unspecified other impact via a crafted jpg file.

libjpeg-turbo 3.2.0 contains an integer division-by-zero vulnerability in the PNG loader. When processing a valid indexed-color PNG image with a non-gray palette through tj3LoadImage12() or tj3LoadImage16() using the default pixel format, the application may trigger a division-by-zero in alloc_sarray(), causing a SIGFPE and denial of service.

A vulnerability in libjpeg-turbo causes a null pointer dereference in jcopy_sample_rows() when processing a crafted input file. This can lead to a crash of the application using the library.
