Adobe Acrobat Reader: Buffer overflow vulnerability — GLSA 200412-12

Adobe Acrobat Reader is vulnerable to a buffer overflow that could lead to remote execution of arbitrary code.

Affected packages

Package 	app-text/acroread on all architectures
Affected versions 	< 5.10
Unaffected versions 	>= 5.10

Background

Adobe Acrobat Reader is a utility used to view PDF files.

Description

A buffer overflow has been discovered in the email processing of Adobe Acrobat Reader. This flaw exists in the mailListIsPdf function, which checks if the input file is an email message containing a PDF file.

Impact

A remote attacker could send the victim a specially-crafted email and PDF attachment, which would trigger the buffer overflow and possibly lead to the execution of arbitrary code with the permissions of the user running Adobe Acrobat Reader.

Workaround

There is no known workaround at this time.

Resolution

All Adobe Acrobat Reader users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-text/acroread-5.10"
