[GLSA-200406-16] Apache 1.3: Buffer overflow in mod_proxy |
||
Apache 1.3: Buffer overflow in mod_proxy Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200406-16 (Apache 1.3: Buffer overflow in mod_proxy) A bug in the proxy_util.c file may lead to a remote buffer overflow. To trigger the vulnerability a possible hacker would have to get mod_proxy to connect to a malicous server which returns an invalid (negative) Content-Length. Impact A possible hacker could cause a Denial of Service as the Apache child handling the request, which will die and under some circumstances execute arbitrary code as the user running Apache, usually "apache". Workaround There is no known workaround at this time. All users are encouraged to upgrade to the latest available version: References: http://www.guninski.com/modproxy1.html http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0492 Solution: Apache 1.x users should upgrade to the latest version of Apache: # emerge sync # emerge -pv ">=net-www/apache-1.3.31-r2" # emerge ">=net-www/apache-1.3.31-r2" Network Security Threat Level: Medium Networks Security ID: Vulnerability Assessment Copyright: (C) 2005 Michel Arboi |
