Ubuntu Security Notice 6857-1 - Joshua Rogers discovered that Squid incorrectly handled requests with the urn: scheme. A remote attacker could possibly use this issue to cause Squid to consume resources, leading to a denial of service. This issue only affected Ubuntu 16.04 LTS. It was discovered that Squid incorrectly handled SSPI and SMB authentication. A remote attacker could use this issue to cause Squid to crash, resulting in a denial of service, or possibly obtain sensitive information. This issue only affected Ubuntu 16.04 LTS.
A buffer over-read was discovered in libntlmauth in Squid 2.5 through 5.6. Due to incorrect integer-overflow protection, the SSPI and SMB authentication helpers are vulnerable to reading unintended memory locations. In some configurations, cleartext credentials from these locations are sent to a client. This is fixed in 5.7.
