The remote host is missing an update to gv announced via advisory DSA 1214-2. The original update provided in DSA 1214-1 was insufficient this update corrects this. For reference the original advisory below: Renaud Lifchitz discovered that gv, the PostScript and PDF viewer for X, performs insufficient boundary checks in the Postscript parsing code, which allows the execution of arbitrary code through a buffer overflow.

For the stable distribution (sarge) this problem has been fixed in version 3.6.1-10sarge2. For the upcoming stable distribution (etch) this problem has been fixed in version 3.6.2-2. For the unstable distribution (sid) this problem has been fixed in version 3.6.2-2. We recommend that you upgrade your gv package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201214-2
