Arch Linux Security Advisory ASA-201711-4 ========================================= Severity: High Date : 2017-11-01 CVE-ID : CVE-2017-14685 CVE-2017-14686 CVE-2017-14687 CVE-2017-15587 Package : mupdf Type : arbitrary code execution Remote : No Link : https://security.archlinux.org/AVG-458 Summary ======= The package mupdf before version 1.11-5 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 1.11-5. # pacman -Syu "mupdf>=1.11-5" The problems have been fixed upstream but no release is available yet. Workaround ========== None. Description =========== - CVE-2017-14685 (arbitrary code execution) Artifex MuPDF 1.11 allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .xps file. 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 (arbitrary code execution) Artifex MuPDF 1.11 allows attackers to execute arbitrary code or cause a denial of service via a crafted .xps file. 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 (arbitrary code execution) Artifex MuPDF 1.11 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 (arbitrary code execution) An integer overflow leading to an out-of-bounds wrte has been found in mupdf <= 1.11. The parsing of a crafted PDF might allow an attacker to write controlled data to an arbitrary location in memory when performing truncated xref checks. Impact ====== An attacker is able to execute arbitrary code on the affected host by providing a maliciously-crafted .xps or .pdf file.
