Therefore, StackGuard's protection should not be relied upon to prevent exploitation of this vulnerability, though it may mitigate a specific exploit, should one appear. It is beleived this flaw is remotely exploitable. It is not known at this time if the Immunix GLibC system library is vulnerable to a similar flaw. Immunix would like to thank Janusz for working with vendors to solve this issue in a timely manner.
