Vulnerability from csaf_redhat - Published: 2002-07-12 23:00 - Updated: 2025-11-21 17:24
Summary
Red Hat Security Advisory: apache security update
Severity
Moderate
Notes
Topic: The Apache Web server contains a security vulnerability which can be used to launch a denial of service (DoS) attack or, in some cases, allow remote code execution.
Details: Versions of the Apache Web server up to and including 1.3.24 contain a bug in the routines which deal with requests using "chunked" encoding. A carefully crafted invalid request can cause an Apache child process to call the memcpy() function in a way that will write past the end of its buffer, corrupting the stack. On some platforms this can be remotely exploited -- allowing arbitrary code to be run on the server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-0392 to this issue. All users of Apache should update to these errata packages to correct this security issue.

CVE-2002-0392

Apache 1.3 through 1.3.24, and Apache 2.0 through 2.0.36, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a chunk-encoded HTTP request that causes Apache to use an incorrect size.
