Off-by-one error in the inet_network function in libbind in ISC BIND 9.4.2 and earlier, as used in libc in FreeBSD 6.2 through 7.0-PRERELEASE, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted input that triggers memory corruption.

(There is total information disclosure, resulting in all system files being revealed.)
(There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the entire system being compromised.)
(There is a total shutdown of the affected resource. The attacker can render the resource completely unavailable.)
(Specialized access conditions or extenuating circumstances do not exist. Very little knowledge or skill is required to exploit. )
(Authentication is not required to exploit the vulnerability.)

This issue did not affect the versions of GNU libc as shipped with Red Hat Enterprise Linux 2.1, 3, 4, or 5.
This issue affects the versions of libbind as shipped with Red Hat Enterprise Linux 2.1, 3, 4, and 5, however the vulnerable function is not used by any shipped applications. The Red Hat Security Response Team has therefore rated this issue as having low security impact, a future update may address this flaw.
An update to Red Hat Enterprise Linux 5 was released to correct this issue:
