The remote Debian host is missing a security-related update.
An off-by-one flaw, leading to a heap-based buffer overflow (CVE-2014-8157 ), and an unrestricted stack memory use flaw (CVE-2014-8158 ) were found in JasPer, a library for manipulating JPEG-2000 files. A specially crafted file could cause an application using JasPer to crash or, possibly, execute arbitrary code.
Upgrade the jasper packages. For the stable distribution (wheezy), these problems have been fixed in version 1.900.1-13+deb7u3. For the upcoming stable distribution (jessie) and the unstable distribution (sid), these problems will be fixed soon.
