CVE-2019-12527 (retired)

Priority
Description
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.
Notes
 mdeslaur> code in 3.5 is different and doesn't look vulnerable.
