Synopsis

========

 

Multiple memory management errors in JasPer might lead to execution of

arbitrary code via jpeg2k files.

 

Background

==========

 

The JasPer Project is an open-source initiative to provide a free

software-based reference implementation of the codec specified in the

JPEG-2000 Part-1 (jpeg2k) standard.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 media-libs/jasper < 1.900.1-r3 >= 1.900.1-r3

 

Description

===========

 

Marc Espie and Christian Weisgerber have discovered multiple

vulnerabilities in JasPer:

 

* Multiple integer overflows might allow for insufficient memory

allocation, leading to heap-based buffer overflows (CVE-2008-3520).

 

* The jas_stream_printf() function in libjasper/base/jas_stream.c

uses vsprintf() to write user-provided data to a static to a buffer,

leading to an overflow (CVE-2008-3522).

 

Impact

======

 

Remote attackers could entice a user or automated system to process

specially crafted jpeg2k files with an application using JasPer,

possibly leading to the execution of arbitrary code.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All JasPer users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=media-libs/jasper-1.900.1-r3"
