CVE-2011-1499 [LOW] CVE-2011-1499 CVE-2011-1843 tinyproxy: multiple flaws corrected in version 1.8.3
CVE-2011-1499 CVE-2011-1843 tinyproxy: multiple flaws corrected in version 1.8.3
It was reported [1] that tinyproxy prior to version 1.8.3, when configured to allow a network range (i.e. "Allow 192.168.0.0/24" versus the default "Allow 127.0.0.1"), would allow any connections from any IP address, turning it into an open proxy. If tinyproxy were configured with one or more Allow statements that use an IP range, this would occur.
This has been fixed upstream [2] and affects the versions of tinyproxy as provided by Fedora and EPEL.
