Back to Red Hat Linux 6.0 Errata

Package squid Synopsis Potential misuse of squid cachemgr.cgi Advisory ID RHSA-1999:025-01 Issue Date 1999-07-29 Keywords squid cachemgr.cgi connect 1. Topic: cachemgr.cgi, the manager interface to Squid, is installed by default in /home/httpd/cgi-bin. If a web server (such as apache) is running, this can allow remote users to sent connect() requests from the local machine to arbitrary hosts and ports. 2. Bug IDs fixed: 3. Relevant releases/architectures: Red Hat Linux 6.0, all architectures 4. Obsoleted by: None 5. Conflicts with: None 6. RPMs required: Intel: ftp://updates.redhat.com/6.0/en/os/i386/ squid-2.2.STABLE4-5.i386.rpm Alpha: ftp://updates.redhat.com/6.0/en/os/alpha/ squid-2.2.STABLE4-5.alpha.rpm SPARC: ftp://updates.redhat.com/6.0/en/os/sparc/ squid-2.2.STABLE4-5.sparc.rpm Source: ftp://updates.redhat.com/6.0/en/os/SRPMS squid-2.2.STABLE4-5.src.rpm 7. Problem description: A remote user could enter a hostname/IP address and port number, and the cachemgr CGI would attempt to connect to that host and port, printing the error if it fails. 8. Solution: For each RPM for your particular architecture, run: rpm -Uvh filename where filename is the name of the RPM. Alternatively, you can simply disable the cachemgr.cgi, by editing your http daemons access control files or deleting/moving the cachemgr.cgi binary. After installing the rpm, please restart squid by typing: /etc/rc.d/init.d/squid restart 9.
