SynopsisThe remote Debian host is missing a security update.
DescriptionSeveral security vulnerabilities were discovered in the JasPer JPEG-2000 library.
Gustavo Grieco discovered an integer overflow vulnerability that allows remote attackers to cause a denial of service or may have other unspecified impact via a crafted JPEG 2000 image file.
Josselin Feist found a double-free vulnerability that allows remote attackers to cause a denial of service (application crash) by processing a malformed image file.
Gustavo Grieco discovered a NULL pointer dereference vulnerability that can cause a denial of service via a crafted BMP image file. The update also includes the fixes for the related issues CVE-2016-8884 and CVE-2016-8885 which complete the patch for CVE-2016-8690.
It was discovered that jasper does not properly release memory used to store image tile data when image decoding fails which may lead to a denial of service.
A heap-based buffer over-read was found related to the jas_image_ishomosamp function that could be triggered via a crafted image file and may cause a denial of service (application crash) or have other unspecified impact.
For Debian 8 'Jessie', these problems have been fixed in version 1.900.1-debian1-2.4+deb8u4.
We recommend that you upgrade your jasper packages.
