Description

Background

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

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"
