The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2023:0048-1 advisory.

  - GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. Prior to     version 1.2.0, multiple out-of-bounds reads when decoding NTLM fields can trigger a denial of service. A     32-bit integer overflow condition can lead to incorrect checks of consistency of length of internal     buffers. Although most applications will error out before accepting a singe input buffer of 4GB in length     this could theoretically happen. This vulnerability can be triggered via the main `gss_accept_sec_context`     entry point if the application allows tokens greater than 4GB in length. This can lead to a large, up to     65KB, out-of-bounds read which could cause a denial-of-service if it reads from unmapped memory. Version     1.2.0 contains a patch for the out-of-bounds reads. (CVE-2023-25563)

  - GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. Prior to     version 1.2.0, memory corruption can be triggered when decoding UTF16 strings. The variable `outlen` was     not initialized and could cause writing a zero to an arbitrary place in memory if `ntlm_str_convert()`     were to fail, which would leave `outlen` uninitialized. This can lead to a denial of service if the write     hits unmapped memory or randomly corrupts a byte in the application memory space. This vulnerability can     trigger an out-of-bounds write, leading to memory corruption. This vulnerability can be triggered via the     main `gss_accept_sec_context` entry point. This issue is fixed in version 1.2.0. (CVE-2023-25564)

  - GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. Prior to     version 1.2.0, an incorrect free when decoding target information can trigger a denial of service. The     error condition incorrectly assumes the `cb` and `sh` buffers contain a copy of the data that needs to be     freed. However, that is not the case. This vulnerability can be triggered via the main     `gss_accept_sec_context` entry point. This will likely trigger an assertion failure in `free`, causing a     denial-of-service. This issue is fixed in version 1.2.0. (CVE-2023-25565)

  - GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. Prior to     version 1.2.0, a memory leak can be triggered when parsing usernames which can trigger a denial-of-     service. The domain portion of a username may be overridden causing an allocated memory area the size of     the domain name to be leaked. An attacker can leak memory via the main `gss_accept_sec_context` entry     point, potentially causing a denial-of-service. This issue is fixed in version 1.2.0. (CVE-2023-25566)

  - GSS-NTLMSSP, a mechglue plugin for the GSSAPI library that implements NTLM authentication, has an out-of-     bounds read when decoding target information prior to version 1.2.0. The length of the `av_pair` is not     checked properly for two of the elements which can trigger an out-of-bound read. The out-of-bounds read     can be triggered via the main `gss_accept_sec_context` entry point and could cause a denial-of-service if     the memory is unmapped. The issue is fixed in version 1.2.0. (CVE-2023-25567)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
