Vulnerability  : insecure temporary file
Problem-Type   : local
Debian-specific: no
CVE ID         : CVE-2006-4802
Debian Bug     : 334350

Eric Romang discovered that the flexbackup backup tool creates temporary
files in an insecure manner, which allows denial of service through a
symlink attack.

For the stable distribution (sarge) this problem has been fixed in
version 1.2.1-2sarge1

For the upcoming stable distribution (etch) this problem has been
fixed in version 1.2.1-3.

For the unstable distribution (sid) this problem has been fixed in
version 1.2.1-3.

We recommend that you upgrade your flexbackup package.
