Multiple memory management errors in JasPer might lead to execution of arbitrary code via jpeg2k files.

2.  Impact Information


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.


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).


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.

3.  Resolution Information


There is no known workaround at this time.


All JasPer users should upgrade to the latest version:

Code Listing 3.1: Resolution

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