Debian Security Advisory DSA 1214-2                    security@debian.org

Package        : gv
Vulnerability  : buffer overflow
Problem-Type   : local(remote)
Debian-specific: no
CVE ID         : CVE-2006-5864
Debian Bug     : 398292

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.
