CVE-2017-7975

Estado: ModificadaAlta (7.8)—

Artifex jbig2dec 0.13, as used in Ghostscript, allows out-of-bounds writes because of an integer overflow in the jbig2_build_huffman_table function in jbig2_huffman.c during operations on a crafted JBIG2 file, leading to a denial of service (application crash) or possibly execution of arbitrary code.
