Description Vincent Danen 2011-04-07 17:11:40 EDT

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.

Comment 1 Vincent Danen 2011-04-08 16:49:56 EDT

This was assigned the name CVE-2011-1499.

Comment 2 Vincent Danen 2011-05-03 11:03:30 EDT

Common Vulnerabilities and Exposures assigned an identifier CVE-2011-1843 to
the following vulnerability:

Name: CVE-2011-1843
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-1843
Assigned: 20110502
Reference: https://banu.com/bugzilla/show_bug.cgi?id=90
Reference: https://banu.com/cgit/tinyproxy/diff/?id=97b9984484299b2ce72f8f4fc3706dab8a3a8439

Integer overflow in conf.c in Tinyproxy before 1.8.3 might allow
remote attackers to bypass intended access restrictions in
opportunistic circumstances via a TCP connection, related to improper
handling of invalid port numbers.


The above is a related but slightly different issue (note the same bug, but different commits).
