"The remote SUSE Linux SUSE15 host has a package installed that is affected by multiple vulnerabilities as referenced in
the openSUSE-SU-2023:0018-1 advisory.

  - net/http in Go before 1.16.12 and 1.17.x before 1.17.5 allows uncontrolled memory consumption in the
    header canonicalization cache via HTTP/2 requests. (CVE-2021-44716)

  - Go before 1.16.12 and 1.17.x before 1.17.5 on UNIX allows write operations to an unintended file or
    unintended network connection as a consequence of erroneous closing of file descriptor 0 after file-
    descriptor exhaustion. (CVE-2021-44717)

  - syslabs/sif is the Singularity Image Format (SIF) reference implementation. In versions prior to 2.8.1the
    `github.com/sylabs/sif/v2/pkg/integrity` package did not verify that the hash algorithm(s) used are
    cryptographically secure when verifying digital signatures. A patch is available in version >= v2.8.1 of
    the module. Users are encouraged to upgrade. Users unable to upgrade may independently validate that the
    hash algorithm(s) used for metadata digest(s) and signature hash are cryptographically secure.
    (CVE-2022-39237)

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