Debian DLA-942-1 : jbig2dec security update

high Nessus Plugin ID 100177

Synopsis

The remote Debian host is missing a security update.

Description

CVE-2017-7885 Artifex jbig2dec 0.13 has a heap-based buffer over-read leading to denial of service (application crash) or disclosure of sensitive information from process memory, because of an integer overflow in the jbig2_decode_symbol_dict function in jbig2_symbol_dict.c in libjbig2dec.a during operation on a crafted .jb2 file.

CVE-2017-7975 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.

CVE-2017-7976 Artifex jbig2dec 0.13 allows out-of-bounds writes and reads because of an integer overflow in the jbig2_image_compose function in jbig2_image.c during operations on a crafted .jb2 file, leading to a denial of service (application crash) or disclosure of sensitive information from process memory.

For Debian 7 'Wheezy', these problems have been fixed in version 0.13-4~deb7u2.

We recommend that you upgrade your jbig2dec packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
