FreeBSD : chicken -- multiple vulnerabilities (c6932dd4-eaff-11e6-9ac1-a4badb2f4699)

High Nessus Plugin ID 96995


The remote FreeBSD host is missing a security-related update.


Peter Bex reports :

A buffer overflow error was found in the POSIX unit's procedures process-execute and process-spawn.

Additionally, a memory leak existed in this code, which would be triggered when an error is raised during argument and environment processing.

Irregex versions before 0.9.6 contain a resource exhaustion vulnerability: when compiling deeply nested regexes containing the '+' operator due to exponential expansion behaviour.


Update the affected package.
