http://security.gentoo.org/

Severity:	normal
Title:	Adobe Acrobat Reader: Buffer overflow vulnerability
Date:	07/11/2005
Bugs:	#98101
ID:	200507-09

Synopsis

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

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-text/acroread	<= 5.10	>= 7.0	All supported architectures

Description

A buffer overflow has been discovered in the UnixAppOpenFilePerform() function, which is called when Adobe Acrobat Reader tries to open a file with the "\Filespec" tag.

Impact

By enticing a user to open a specially crafted PDF document, a remote attacker could exploit this vulnerability to execute arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

Since Adobe will most likely not update the 5.0 series of Adobe Acrobat Reader for Linux, all users should upgrade to the latest available version of the 7.0 series:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/acroread-7.0"
