Gentoo Linux Security Advisory GLSA 200812-18


                                        http://security.gentoo.org/

Severity: Normal
Title: JasPer: User-assisted execution of arbitrary code
Date: December 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
-------------------------------------------------------------------

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 &quot;&gt;=media-libs/jasper-1.900.1-r3&quot;
