Description of problem:
Sendmail versions prior to 8.11.4 have a documented race condition having to do with signal handling which can lead to heap corruption and a 
possible local root exploit (none are currently known).

How reproducible:
Didn't try

Steps to Reproduce:


Additional info:

Although difficult to expliot, this is a potentially serious bug which IMHO warrants an errata with packages for all currently supported versions to 
upgrade to 8.11.4.
