Debian Security Advisory DSA-1483-1                security@xxxxxxxxxx
http://www.debian.org/security/                         Noah Meyerhans

- ------------------------------------------------------------------------

Package        : net-snmp
Vulnerability  : design error
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2007-5846

The SNMP agent (snmp_agent.c) in net-snmp before 5.4.1 allows remote
attackers to cause a denial of service (CPU and memory consumption)
via a GETBULK request with a large max-repeaters value.

For the stable distribution (etch), this problem has been fixed in
version 5.2.3-7etch2

For the unstable and testing distributions (sid and lenny,
respectively), this problem has been fixed in version 5.4.1~dfsg-2

We recommend that you upgrade your net-snmp package.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.


Debian GNU/Linux 4.0 alias etch
- -------------------------------

Stable updates are available for alpha, amd64, arm, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
