Severity:	normal
Title:	Adobe Reader: User-assisted execution of arbitrary code
Date:	04/18/2009
Bugs:	#259992
ID:	200904-17

Synopsis

Adobe Reader is vulnerable to execution of arbitrary code.

Background

Adobe Reader (formerly Adobe Acrobat Reader) is a closed-source PDF reader.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-text/acroread	< 8.1.4	>= 8.1.4	All supported architectures

Description

Multiple vulnerabilities have been discovered in Adobe Reader:

Alin Rad Pop of Secunia Research reported a heap-based buffer overflow when processing PDF files containing a malformed JBIG2 symbol dictionary segment (CVE-2009-0193).
A buffer overflow related to a non-JavaScript function call and possibly an embedded JBIG2 image stream has been reported (CVE-2009-0658).
Tenable Network Security reported a stack-based buffer overflow that can be triggered via a crafted argument to the getIcon() method of a Collab object (CVE-2009-0927).
Sean Larsson of iDefense Labs reported a heap-based buffer overflow when processing a PDF file containing a JBIG2 stream with a size inconsistency related to an unspecified table (CVE-2009-0928).
Jonathan Brossard of the iViZ Security Research Team reported an unspecified vulnerability related to JBIG2 and input validation (CVE-2009-1061).
Will Dormann of CERT/CC reported a vulnerability lading to memory corruption related to JBIG2 (CVE-2009-1062).

Impact

A remote attacker could entice a user to open a specially crafted PDF document, possibly leading to the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All Adobe Reader users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/acroread-8.1.4"
