The remote host is missing updates announced in advisory CLA-2002:542.
gv is a program which uses the Ghostscript PostScript interpreter to display PostScript and PDF documents under the X Window System. kghostview is a KDE application which does the same.
Zen Parse found[1] a buffer overflow vulnerability in gv version 3.5.8 and earlier. kghostview (from kdegraphics versions prior to 3.0.4) is also affected, since it has some code derived from the same project. An attacker can exploit this vulnerability by creating a carefully crafted pdf file that, when opened by gv or kghostview, causes the execution of arbitrary code.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2002-0838 to this issue[2].
Solution: The apt tool can be used to perform RPM package upgrades by running 'apt-get update' followed by 'apt-get upgrade'
