Details

It was discovered that JasPer did not correctly handle memory allocation
when parsing certain malformed JPEG2000 images. If a user were tricked into
opening a specially crafted image with an application that uses libjasper,
an attacker could cause a denial of service and possibly execute arbitrary
code with the user's privileges. (CVE-2008-3520)

It was discovered that JasPer created temporary files in an insecure way.
Local users could exploit a race condition and cause a denial of service in
libjasper applications.
(CVE-2008-3521)

It was discovered that JasPer did not correctly handle certain formatting

of service and possibly execute arbitrary code with the user's privileges.
