Gentoo Linux Security Advisory

Title: JasPer: User-assisted execution of arbitrary code (GLSA 200812-18)
Severity: normal
Exploitable: remote
Date: December 16, 2008
Bug(s): #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: media-libs/jasper
Vulnerable: < 1.900.1-r3
Unaffected: >= 1.900.1-r3
Architectures: 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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/jasper-1.900.1-r3"
