1. Topic:
New nmh packages are available to fix a security problem in mime
header parsing.
2. Relevant releases/architectures:
Red Hat Linux 5.2 – i386 alpha sparc
Red Hat Linux 6.0 – i386 alpha sparc

3. Problem description:
By creating specially formed MIME headers, it was possible to
have nmh’s ‘mhshow’ utility execute arbitrary shell code.
It is recommended that all users of nmh upgrade to the fixed
packages.
4. Solution:
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
