Debian DLA-2796-1 : jbig2dec - LTS security update

critical Nessus Plugin ID 154735


The remote Debian host is missing one or more security-related updates.


The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2796 advisory.

- libjbig2dec.a in Artifex jbig2dec 0.13, as used in MuPDF and Ghostscript, has a NULL pointer dereference in the jbig2_huffman_get function in jbig2_huffman.c. For example, the jbig2dec utility will crash (segmentation fault) when parsing an invalid file. (CVE-2017-9216)

- jbig2_image_compose in jbig2_image.c in Artifex jbig2dec before 0.18 has a heap-based buffer overflow.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade the jbig2dec packages.

For Debian 9 stretch, these problems have been fixed in version 0.13-4.1+deb9u1.
