A vulnerability has been found in ISC DHCP up to 3.0.1rc14 on Unix (Network Management Software) and classified as critical. This vulnerability affects the function vsprintf. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The DHCP daemon (DHCPD) for ISC DHCP 3.0.1rc12 and 3.0.1rc13, when compiled in environments that do not provide the vsnprintf function, uses C include files that define vsnprintf to use the less safe vsprintf function, which can lead to buffer overflow vulnerabilities that enable a denial of service (server crash) and possibly execute arbitrary code.

The bug was discovered 06/22/2004. The weakness was shared 06/22/2004 by Gregory Duchemin and Solar Designer (Website). The advisory is shared for download at isc.org. This vulnerability was named CVE-2004-0461 since 05/12/2004. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are known technical details, but no exploit is available.
