Heap-based buffer overflow in proxy_util.c for mod_proxy in Apache 1.3.25 to 1.3.31 allows remote attackers to cause a denial of service (process crash) and possibly execute arbitrary code via a negative Content-Length HTTP header field, which causes a large amount of data to be copied.

Security readout for executives and security teams

CVE-2004-0492 is an old Apache HTTP Server mod_proxy flaw. A remote attacker could crash an affected server, and the CVE states arbitrary code execution may be possible. Exposure matters mainly for legacy Apache 1.3 deployments where proxy functionality remains enabled. Likely exposure is limited to very old Apache 1.3.25-1.3.31 systems with mod_proxy enabled. Modern Apache branches are not identified as affected in the provided bundle. Prioritize remediation if any internet-facing legacy Apache 1.3 proxy service still exists. For most organizations this is an asset-discovery and legacy-retirement issue rather than an emergency on current platforms. Mitigation focus: Inventory Apache HTTP Server versions and confirm whether mod_proxy is enabled.; Apply vendor security updates or upgrade away from Apache 1.3.25-1.3.31.; Disable mod_proxy where proxy functionality is not required..
