NVD Description

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

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.
