jbig2dec: Multiple issues (4.1)
Last modified: 2019-04-11 19:23:49 CEST
Upstream Debian package version 0.13-4~deb7u1 fixes: * Heap-buffer overflow due to Integer overflow in jbig2_image_new function (CVE-2016-9601) libjbig2dec0 is maintained because ghostscript and okular depend on it.
Upstream Debian package version 0.13-4~deb7u2 fixes: * 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-2017-7885) * 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-2017-7975) * 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. (CVE-2017-7976)
For some reason UCS 4.x ships version 0.11 of this package. We should also check UCS 3.3-1 in case UCS 4.x actually is affected.
This issue has been filed against UCS 4.1. UCS 4.1 is out of maintenance and many UCS components have vastly changed in later releases. Thus, this issue is now being closed. If this issue still occurs in newer UCS versions, please use "Clone this bug" or reopen this issue. In this case please provide detailed information on how this issue is affecting you.
