Fedora 7 : c-ares-1.4.0-1.fc7 (2007-0724)

High Nessus Plugin ID 27676


The remote Fedora host is missing a security update.


There is a vulnerability in c-ares < 1.4.0, caused by predictable DNS 'Transaction ID' field in DNS queries and can be exploited to poison the DNS cache of an application using the library if a valid ID is guessed.


Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected c-ares, c-ares-debuginfo and / or c-ares-devel packages.
