Description Andrej Nemec 2017-10-09 16:09:08 UTC
Multiple vulnerabilities in mupdf received CVEs. It seems that these were discovered on Windows, so they might not be related to the version as shipped in Fedora, but I would like to ask you to check this out, so that we are on the safe side. Thanks!


CVE-2017-14685

Artifex MuPDF 1.11 allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .xps file, related to "Data from Faulting Address controls Branch Selection starting at mupdf+0x000000000016aa61" on Windows. This occurs because xps_load_links_in_glyphs in xps/xps-link.c does not verify that an xps font could be loaded.

CVE-2017-14686

Artifex MuPDF 1.11 allows attackers to execute arbitrary code or cause a denial of service via a crafted .xps file, related to a "User Mode Write AV near NULL starting at wow64!Wow64NotifyDebugger+0x000000000000001d" on Windows. This occurs because read_zip_dir_imp in fitz/unzip.c does not check whether size fields in a ZIP entry are negative numbers.

CVE-2017-14687

Artifex MuPDF 1.11 allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .xps file, related to "Data from Faulting Address controls Branch Selection starting at mupdf+0x000000000016cb4f" on Windows. This occurs because of mishandling of XML tag name comparisons.
