NVD Description

Note: Versions mentioned in the description apply only to the upstream squid3 package and not the squid3 package as distributed by Ubuntu.

An issue was discovered in Squid 4.0.23 through 4.7. When checking Basic Authentication with HttpHeader::getAuth, Squid uses a global buffer to store the decoded data. Squid does not check that the decoded length isn't greater than the buffer, leading to a heap-based buffer overflow with user controlled data.
