The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3531-1 advisory.

  - An issue was discovered in Squid 4.9 through 4.17 and 5.0.6 through 5.6. Due to inconsistent handling of     internal URIs, there can be Exposure of Sensitive Information about clients using the proxy via an HTTPS     request to an internal cache manager URL. This is fixed in 5.7. (CVE-2022-41317)

  - 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. (CVE-2022-41318)
