var-201609-0097
Vulnerability from variot
Heap-based buffer overflow in the pdf_load_mesh_params function in pdf/pdf-shade.c in MuPDF allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a large decode array. MuPDF is prone to a denial-of-service vulnerability. Attackers can exploit this issue to crash the affected application, resulting in denial-of-service conditions. Due to the nature of this issue, code execution may be possible but this has not been confirmed.
Gentoo Linux Security Advisory GLSA 201702-12
https://security.gentoo.org/
Severity: Normal Title: MuPDF: Multiple vulnerabilities Date: February 19, 2017 Bugs: #589826, #590480, #608702, #608712 ID: 201702-12
Synopsis
Multiple vulnerabilities have been found in MuPDF, the worst of which allows remote attackers to execute arbitrary code.
Background
A lightweight PDF, XPS, and E-book viewer.
Affected packages
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/mupdf < 1.10a-r1 >= 1.10a-r1
Description
Multiple vulnerabilities have been discovered in MuPDF. Please review the CVE identifiers referenced below for details.
Impact
A remote attacker could entice a user to open a specially crafted PDF document using MuPDF possibly resulting in the execution of arbitrary code, with the privileges of the process, or a Denial of Service condition.
Workaround
There is no known workaround at this time.
Resolution
