GLSA 200812-18: JasPer: User-assisted execution of arbitrary code

http://security.gentoo.org/

Severity:	normal
Title:	JasPer: User-assisted execution of arbitrary code
Date:	12/16/2008
Bugs:	#222819
ID:	200812-18

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	Architecture(s)
media-libs/jasper	< 1.900.1-r3	>= 1.900.1-r3	All supported architectures

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"
