Two security issues were discovered in mupdf, a lightweight PDF viewer.
CVE-2017-14687 MuPDF allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .xps file. This occurs because of mishandling of XML tag name comparisons.
CVE-2017-15587 An integer overflow was discovered in pdf_read_new_xref_section in pdf/pdf-xref.c
For Debian 7 ‘Wheezy’, these problems have been fixed in version 0.9-2+deb7u4.
We recommend that you upgrade your mupdf 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.
