Artifex · Jbig2Dec · CVE-2017-7975
**Name of the Vulnerable Software and Affected Versions**
Artifex jbig2dec version 0.13
**Description**
The issue is caused by an integer overflow in the `jbig2 build huffman table` function in `jbig2 huffman.c` when processing a crafted JBIG2 file. This can lead to out-of-bounds writes, resulting in a denial of service (application crash) or potentially allowing the execution of arbitrary code.
**Recommendations**
For Artifex jbig2dec version 0.13, consider avoiding the use of crafted JBIG2 files until a patch is available. As a temporary workaround, restrict the processing of JBIG2 files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
