The remote host is missing an update to libimager-perl announced via advisory DSA 1028-1. Kjetil Kjernsmo discovered a bug in libimager-perl, a Perl extension for generating 24 bit images, which can lead to a segmentation fault if it operates on 4-channel JPEG images. The old stable distribution (woody) does not contain this package.
For the stable distribution (sarge) this problem has been fixed in version perl_0.44-1sarge1. For the unstable distribution (sid) this problem has been fixed in version 5.0-1. We recommend that you upgrade your libimager-perl package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201028-1
