Vulnerability details

The vulnerability allows a remote attacker to gain access to potentially sensitive information or crash the server.

The vulnerability exists due to a boundary condition within SSPI and SMB authentication helpers. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system or crash the server.

Successful exploitation of the vulnerability requires that Squid is configured to use NTLM or Negotiate authentication with one of the vulnerable helpers.
