Gentoo Linux Security Advisory

Title: Adobe Reader: User-assisted execution of arbitrary code (GLSA 200904-17)
Severity: normal
Exploitable: remote
Date: April 18, 2009
Bug(s): #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: app-text/acroread
Vulnerable: < 8.1.4
Unaffected: >= 8.1.4
Architectures: 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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/acroread-8.1.4"
