Description Tim Sammut (RETIRED) gentoo-dev

When tinyproxy is configured with ACLs using network/mask notation it incorrectly operates as an open proxy. 

Upstream bug is at $URL, fix/commit at https://banu.com/cgit/tinyproxy/commit/?id=e8426f6662dc467bd1d827100481b95d9a4a23e4, and I don't believe upstream has released a fixed version of the package yet.

The NVD also lists CVE-2011-1843 as fixed in tinyproxy 1.8.3 which I don't see available yet.

CVE-2011-1843 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1843):
  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.

CVE-2011-1499 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1499):
  acl.c in Tinyproxy before 1.8.3, when an Allow configuration setting
  specifies a CIDR block, permits TCP connections from all IP addresses, which
  makes it easier for remote attackers to hide the origin of web traffic by
  leveraging the open HTTP proxy server.
