squid: parsing of header Proxy-Authentication leads to memory corruption

An issue was discovered in Squid 3.3.9 through 3.5.28 and 4.x through 4.7. When Squid is configured to use Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as domain, uri, and qop. Squid checks if this token's value starts with a quote and ends...

squid: improper check for new member in ESIExpression::Evaluate allows for stack buffer overflow

A flaw was found in Squid through version 4.7. When handling the tag esi:when, when ESI is enabled, Squid calls the ESIExpression::Evaluate function which uses a fixed stack buffer to hold the expression. While processing the expression, there is no check to ensure that the stack won't overflow...
