Several methods of causing undesired or unexpected behaviour in programs that make use of non-atomic or non-reentrant operations in signal handling functions have recently been presented in a paper by Michal Zalewski. Due to the implications of this paper, the Sendmail MTA has been found to be susceptible to several possible race condition vulnerabilities.
