Adobe Reader: User-assisted execution of arbitrary code

Adobe Reader: User-assisted execution of arbitrary code Adobe Reader is vulnerable to execution of arbitrary code. acroread April 18, 2009 April 18, 2009: 01 259992 remote 8.1.4 8.1.4

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

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).

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.

There is no known workaround at this time.

All Adobe Reader users should upgrade to the latest version:


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