Description Marcus Meissner 2019-07-12 15:13:56 UTC

CVE-2019-12525

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 with one.
If so, it performs a memcpy of its length minus 2. Squid never checks whether
the value is just a single quote (which would satisfy its requirements), leading
to a memcpy of its length minus 1.
